Is Port Matching A WASTE Of Time?

okay what are we doing today we are going to Port match the intake manifold to these trickflow heads okay and we are now in my world so follow along I'm going to turn the satire back on by the way a little bit of engine Rehab on the gmz online YouTube channel so the block is final machine we've got our deck height sorted out uh cylinders are honed all our parts are in heads are finished we're going to set them on the block with a couple bolts and I'm just going to set the intake manifold on we'll measure the intake gaskets figure out how thick it is and we'll set it on with some shims uh that are about the same thickness and then I'll show you one of one of two ways on how to transfer the ports on the head to the ports on the intake manifold uh this is a dual plane intake where's that intake it's clear over on the bench useless [Music] the trick flow head is actually set up for whatever felpro gasket this is uh and it's actually quite a good match dimensionally so check this out I guess kind of walk through what port matching is which you're going to get to I assume so Port matching is uh getting the ports on your cylinder head uh and the ports on your intake manifold to uh fit one another properly best case scenario your intake manifold is going to have a smaller Port Dimension than your head um and honestly you could uh that would leave you with the choice of leaving it alone or taking it the extra step and then uh hand grinding this to match the ports on the heads and I'm going to show you why we're going to do this um quickly here's our intake gasket it's going to match the head very very well uh there's some slight differences in the corner radius that doesn't matter don't worry about it uh but pay attention to how well this fits okay set this on the intake I'm just going to line it up with the bottom of the ports okay oh gray on Gray in a dark shop is a little hard to see and then that same thing wow look at that this this set is actually quite screwed up so this port lines up pretty well on this outside wall but there's a big old step here um nice step on the top of the port but then it's neighbor big old step here uh big old step there they don't match you can be smaller in the intake and not hurt performance drastically the flip side of that would be the ports could be too big on your intake manifold and the ports are uh compared to the ports on the cylinder head um that will hurt hurt horsepower because you're going to have a reverse step uh that's going to impede airf flow so the goal is to get things to transition with one another these are different components made by different people uh they might not play nice with each other and then when you're going around and remachining things especially on a V8 engine or V6 engine you're going to change the relationship of how Parts sit with one another as well so if you deck your heads mile you'll have to Deck the in the intake to match otherwise it's going to sit up higher on the engine and you'll get some Port misalignment so right now we're going to set these onto the block with the head gaskets uh with a couple bolts get the intake set on and we'll figure out our Port match okay that doesn't look like the right torque sequence uh there's a video on my YouTube channel that has the proper response to the guys that are going to comment about the imper tool yeah is that a wobbly socket on top of it it is a wobbly socket all right look at that don't you think you're getting ahead of yourself a little bit Yeah I dad things uh want to live in the same space as other things doesn't quite work it doesn't quite work I need to use the combo Square to scribe lines that represent the sides of the ports so we'll have to pull the heads back off but we'll put some dyum on [Laughter] them so you either would have needed a to do that that first or a smaller Square yes a smaller Square would have worked great in this in this situation and then I offered to cut it but I changed my mind cuz it's not my tool I would have been happy to tell the cleaning guy congratulations you're getting a new combination Square I'd just be worried like that's the type of thing that you cut it up and then you find out that it was Grandpa's tool there's like Nostalgia attached to it yes okay so is that sentimental value was that the thought process yes oh okay all right so we won't be chopping up Grandpa cleaning guys treasured it's probably not it's probably just sare a Harbor Freight special yes very much so could have been the Harbor Freight special hey Dad yeah is this squar anything special no could we buy you a new one and modify this one modify it all righty cleaning guy says cut it so you want with it that's cheap one I got well I just I was I told him to cut it and then I was like wait what if it's like something that grandpa had or there's some kind of sentimental value to it somewhere around here maybe out in the other shed is one my dad had but that's special okay well we'll chop it up then okay he he can't it's too long to measure what he needs to or to use it as a a guide for his scribe so I will not be pulling the heads back off we're not ahead of ourselves no go ahead and cut it the hair looks kind of funny but look it's real I've got some really he got more than him you do you you going to get a two pay too do you think I need one no I don't like that you think that's about as straight as I am probably so custom engines custom tools terrible quality to Quality yeah that looks good enough okay now we have all the tools we need so I've got Dam on there I'm going to go inscribe lines uh right along either side of the intake ports and I'm going to bring them all the way up to the top of the cylinder head I actually need to add some Dum up here and you'll see exactly why um uh once once I get to that step the Dy and police are going to show up and go you put too much dye on that what happens with too much I have no idea if you could let me know in the comments it's less to Spill the next time you drop that bottle yeah do you have some uh some dyam accident spots FL around the shop my uh the blue that was in the with the little felt top oh the beac no I've never did they quit making that they're out of business wasn't that the good stuff that was the good stuff now we can't get good layout die so I'm going to use a combo square and bring it right up to the valve cover rail we'll lock that down um another thing I've got is a sharpened piece of tungsten you just need a scribe uh don't be afraid this little scratch isn't going to hurt anything line up your square with the port and carry your line all the way up to the top close enough whoa don't do that okay and repeat for all the rest of the holes okay so is this another thing you learned at a job or online by doing a little bit of both I watched watched other people do this um asked a lot of questions some of them got answered uh I actually sought out a lot of information myself and if I didn't get an answer on a question question I'd go and read as many textbooks as I could and depending on how old those textbooks are you might have to curate what information you absorb out of him but even old information is good information unless it's knurling unless it's [Laughter] nuring uh when you're when you first start out uh porting one of the best things you can do is scribe out lines and that will give you a nice visual representation uh of how to grind and where to grind your mind's eye visualizes what you're going for but until you've got the uh muscle memory worked out and uh you're practiced you probably won't be able to grind a straight line uh freehand uh for a very long time it's kind of a a thing that requires a lot of practice a lot of practice many many long nights uh doing mediocre work uh and learning how to do a fine job so I missed this Mark just slightly but it's not going to be a big deal I tend to grind the intakes just shy of this opening anyways okay okay so now I've got all my vertical lines scribed out uh the next step is to take did I yeah oh good thing I'm here yep I helped you're hired um oh okay that's actually something good to talk about I have missed lines a handful of times you can actually just uh uh take pick up a measurement from the other head and use your calipers and Scribe out the uh scribe out that line um if the port layout is symmetrical uh you can actually even just scribe out one port and then go by bore spacing right to each individual port and it should if everything's accurate it should uh repeat very well uh so when you're grinding a head from scratch that's actually not a bad way to uh lay out your ports especially if you know everything um everything's going to end up being really custom and you don't really have you're not really going any for anything in particular um so there's a freedom in how you grind and uh you know what what your finished product is going to look like so we're going to do the the same thing with the roof and the floor of the port I have no idea how straight that is that way it is what it is it doesn't need to be that straight across 4 in it's not a big deal oh sure so this is the used manifold that was on the 413 when it came in um but thought it was actually going to work out for this application yeah it's actually the intake I would have picked and it's not horribly used uh somebody got a little overzealous trying to get it to fit on those original heads which were uh decked 100 th000 and that's why their bolt holes didn't line up unfortunately it's uh or fortunately it's only ugly and they only egged out this side the actual top of the manifold uh the the hole is still original so I don't really understand what they were trying to achieve it was probably kind of a funny angle or something and they thought they could just just do the bottom side where it was hitting yeah I'm sure uh it's strange if only we could all know what goes through the minds of the last guy I was the last guy once upon a time so you know what can you do uh it's a little more emphasized on this side they were a touch more successful at their uh clearancing now the proper way to get an intake manifold to fit when the bolt holes don't line up uh especially when they're a little bit too low uh is to Deck the intake manifold and then that'll actually bring it down lower into the V uh when you set an intake on and it's misaligned uh the bolt holes are misaligned there's a good chance that the ports are also aligned so it's not uncommon that we'll take an intake manifold uh brand new out of the box set it onto an aftermarket head and uh just just toy that we're going to have to cut 60 or 80,000 off of the surface to get the ports to line up um and it seems like a scary number but when you're tolerance stacking between your block Machining and your uh cylinder heads that came from one Supply fire and your intake that came from another uh things probably aren't going to fit or the likelihood that parts are going to are not going to fit can become quite High okay so now all my vertical lines are going to get transferred to the outside of the casting and then I'll use that same combo square and then transfer the uh transfer the Scribe Mark here up along the port and then since that gasket happens to actually uh match quite well we might even use that to reference uh but since we don't have a bolt hole for visual ref uh reference we might we probably won't do that okay seems straightforward enough this is very straightforward you seem a little uncomfortable Nick it's just not something I've had the opportunity to learn before uh you know there's a lot of people that uh race John deers right oh yeah whole community of my dad's people my dad's people my Farmer people yeah okay so I've got my line scribed out we're not going to set the intake on the motor using the actual gaskets I'm going to get the measurements of the gas gasket thickness um and then we're going to find some shims to rigidly mount it to the uh to the engine um so just with the caliper I'm getting about 65 5000 uh and then the there's a metal shim that goes between these gaskets that also acts as the Valley Pan uh that's going to be about 15,000 thick so we'll go for about 70 to 80,000 worth of uh shim uh we'll get it set onto the motor and then we'll go ahead and get our line scribed out okay so I was checking the uh bent up Valley Pan that came in cuz it's so flat and I definitely kind of scratched the heads um nowhere that it matters but that's that's the aesthetic the non- aesthetically pleasing scratches on there that was my fault it's the stuff we deal with because this we Parts should be uh Parts should just fit but never happens yeah um okay so I've got bunch of these spring sh shim uh that's a 60,000 shim and a 15,000 shim uh so that'll give us 75,000 thereabouts 772 um that'll give us the right thickness to represent our gaskets and then that'll get the intake manifold to sit properly on this engine okay just for the mockup I'm going to put some dabs of Grease onto the heads and that'll help hold the shims into place that way it's not the twers job to get this intake set on cuz I'm doing the important job of holding the camera the hard work well you're doing a fine job you should think about doing this for a living I don't think I'd make enough [Laughter] money all right these tubes are empty by the way yeah they were on the Shelf like they weren't empty there's a little bit okay okay get this set on carefully I wish they didn't modify the synthtic manifold still acting a little too professional for my taste it'll come just wait my stress levels are quite low today might be because I'm with with you come on what I don't understand okay it's like a USB no matter which way you put it in the first time it won't go in the second time it won't go in but if you flip it back to the first way it'll go in okay so I've got this set on actually let's go ahead and just get this a little wiggle yeah okay okay that seems like home all right all right so now all of our vertical lines are going to get transferred to the top of the intake manifold it doesn't matter if you miss one or two of the lines it'll be okay I like to just scribe little arrows it's going to be a little hard to see the markings I'm making here but once I get it all scribed out everything I'm doing here will make a lot more sense I'm probably going to get my lines for on the top side scribed out then I'll scribe then I'll use the combo Square or something to uh draw the lines down the intake manifold I'll probably just set the gasket on once I get a representation of where the top of the port lines up okay I scribed some little arrows uh to represent the position of the uh scrip Lins on the head uh onto the intake manifold and then I'm just going to use the Straight Edge and the combo Square to transfer those lines over um I didn't scribe out the lines for the bottom bottom of the port but we'll probably have enough information here to use the gasket or even just use a caliper to uh transfer our measurements over from the head okay we got it scribed out you can see the little arrow point right there and arrow point right there just held that straight edge between them and scribed it let's scribe some lines out and then we'll uh lay the gasket over it and see what that looks like once we're all scribed out okay okay so I've scribed out one side this is what it's going to look look like uh so we're going to flip it over um I went and took a caliper measure measurement and just compared uh my scribe lines to the ports on the actual head and so I know everything here is um is decent so everything's going to line up very well I don't see any areas on the intake uh where the where I'm missing any material I get a little close here but we're not going to know um so it's going to come out very beautiful uh we'll put some nice we'll put about a half inch radius into all the corners unless you're in a situation here where everything already lines up but I'll do my best to make this look very clean and then we'll go through and sand it and make sure it's uh it looks very presentable so I've got to scribe out my lines that go all the way across so all you do is you take your straight edge uh I scribed out these little um arrows on the side of the intake so you just need to get those lined up trace your line whoa don't do that I didn't get it wrong okay right I've got about a 16th to an eigh inch lip at the top of the port that's pretty standard let me find the combo Square I'm sure Grandpa would be very proud to see that his beloved combo square is being used to make horsepower and you're going off the scribed lines again yes I scribed out vertical marks on each set of ports and then I just traced out the uh Port Dimension I just went over stuck the caliper in the heads went from here to here then I went I went from inside of the first Port went from here to here and then I went from here to there and then I went from here to there okay and I repeated it for that for that side uh based off the dimensions that I measured I was able to confirm that my scribe lines were going to be accurate and then I could drop the intake on uh we'll scribe out some marks to reference when we get this thing assembled and we know that the um intake is going to be on there air will be able to tr uh make its way into the motor and it's not going to run into any hard Ledges so got two lines left lines up just fine okay now the last line I need to draw is the Scribe mark across the bottom so now I've got everything scribed out I'm just going to take the port height measurement and I'm going to transfer that to the bottom of the port and it helps when you see that at least the dimension looks like it makes sense if I'm not scribing at a line that's way out over here right so we've got we're doing something right just like we did the first time use the Straight Edge line up your two marks and this will be our Port match now I got to make noise so now the question is do I make noise in the new shop where the cleanup guy is uh currently trying to learn a new machine or do I grind right here yeah we got to make that decision I guess yeah okay so now it's time to grind the intake manifold uh I use electric Grinders air powerered diagr ERS tend to drive me really nuts they're often really short or they just don't have the torque to get a job done very quickly uh and since this is almost a foot and a half long I can really just hug it really tight to me and really uh really hold it very stable then it's not a stressful deal at all um I I know you've expressed uh a distaste to using die Grinders and grinding on things just every time I try to grind something that's nice yeah it ends up being not nice I I just don't have the control I I haven't I haven't practice but I just don't have the control to to do it but part of my problem might be using a 6inch long air powerered die grinder yeah uh when I was when I was first learning how to grind uh I couldn't afford a nice grinder I think the grinder I tried using was this little cheapy thing I found at Walmart for 20 bucks so and then some random Burr I found at the welding supply so I was definitely there I know exactly what you're talking about and everyone everyone has that exact experience uh so these are high Helix uh single cut burs this isn't the most aggressive flute uh design that I have I have some where it has the half the number of flutes and it just removes material like nobody's business but that's also one of those uh Burrs that can run away from you cuz this style of Burr actually pulls the grinder out of your hands and then puts a BN pile of chips in your lap so you better hold on tight and uh make sure you know where you're shoving your grinder so always good life advice all right so let's get to it [Music] a little slidey here [Applause] [Applause] [Music] [Applause] I can do is my eyes close okay so I'm far from finished here uh porting is quite a messy job uh it tends to get everywhere so whatever the uh I've got the bulk of the material taken out but these Corner radiuses are quite large um I didn't go all the way out to the line uh my burrs are a little on the dull side so it leaves a actually leaves a burr on the edge of the port so a lot of times I'll just take a scraper and I'll break this Burr off and I'll be able to see how far away I am but I'm about 15,000 off of my line on all sides this corner radius is much larger than I'd like um so I'm actually going to move over from this Burr which is a 5/8 diameter Burr um and then I'm going to move to a/ in diameter Burr now you notice that these are different shapes uh this first bur I was using was a is an olive or an oval shape uh this is my general use Burr it's really good for bulk material removal and then I'll use this to get my general shape uh ground out and then what I need to straighten out some lines uh I'll switch to the flame which is what this Burr is um and this helps me grind a nice straight line uh I can do it with the oval and this isn't very bumpy at all but it's just a lot easier when you're using a longer straighter Burr so now I'm going to straighten out these walls bring it closer to uh the final width and then I'll shrink up these Corner radiuses um and then we'll scrape off the Burrs chamfer everything and then I'll just give you a quick preview of what a roughed out Port looks like versus the unported uh pair of Runners here [Applause] [Applause] so check this out now I've switched to that smaller bur you can see how much I shrink that corner radius it's starting to look a lot more like a rectangle which is what the PCH shape is or the entry shape is uh this is a big oval or it's a very rounded corner here and I've almost squared that off so that's the shape I'm going for after we get this uh finished out on all the runners I'll actually sand this and uh get an even finer finish um it'll still be rough to the touch I use 60 grit anywhere from 36 to 60 grit to finish out intakes um if you follow me on Instagram or see any of the stuff I've posted on YouTube you actually you'll you'd actually know that I uh oftentimes will Port an manifold and just leave the bur finish on the uh inside of the intake uh and that isn't necessarily for any other reason other than to often times just save time sanding on a port is really just a visual thing and that's what people want to see and that's often what's referred to as the polishing portion of uh of port and polishing but it's that's kind of fufo stuff and that's what people want to see because shiny means fast so what about stickers stickers are uh guaranteed or power are you about done making a mess out of our shop putting the cleaning guy to work I like having a cleaning guy it's pretty nice huh yeah it is pretty nice I think I'm going to have to take him home yeah and and he's real cheap all you got to do is uh feed him with a banana and he's pretty he's pretty happy there you go I thought that was a Precision pointer that is a that is a pointing device and if I can take that back thanks no get back for work um we're almost done with this intake in fact I've got this one side all roughed out I've got this one side all roughed out uh our basic shape is all ground into the intake manifold brought it right up to the lines we've got very good quarter radius here um and then I came in after I used my roughing burs and then I used this little double cut and just lightly ground the ports and that gave me a little smoother surface finish now the next step is to come in with a cartridge roll uh this is a 60 grit uh what is this made out of it's a ceramic cartridge roll and then what you'll end up with is this and this is what people really want to see all the port walls are very straight the pattern work uh which is the literally the sanding lines that those all blend in from wall to wall um the surface is very uniform you don't see uh very much of any of the old uh uh Burr work so I'll show you what I do there uh we'll get this flipped around finish this other side and then I think what we'll do is we'll get this mounted up in the surfacer and put a little skim cut on the intake manifold uh my burrs are a little on the dull side so they'll leave little Burrs themselves on the corners of the ports that you have to champer off so I used this flat file filed it straight across the intake face and it seemed to only hit here and here so I wonder if we're going to be able to see that uh when we go to surface this a lot of times intake manifolds are surfaced with a little two or 3 inch fly cutter um and sometimes they'll have a big dip in the middle so I want to make sure we're not going to have any intake leak so we'll get this uh skim cut and then uh get it set on the motor and move on with our lives sounds good I am the danger a guy opens his door and gets shot you think out of me no I am the one who knocks [Music] okay good do what are you doing over here Nick so we're going to set this up and just try to skim the intake make sure the surfaces are flat and good like they're supposed to be I ran an indicator across here and it seems pretty wonky so we're just kind of taking an average and we'll touch off over here zero the machine and do a cut I'm just going to start it over here cuz we want to actually touch off over on this side for this one but I want to make sure it's moving when I go across so I don't hit anything just in case or I'll hit something but how common are intake manifolds warped right out of the box you know that far more than I do okay so very it's a very common thing in fact uh most performance circles we'll just take the intake manifolds do whatever work we need to do to them and then just put a skim cut on them just cuz uh often enough we'll find that that wasn't a waste of [Music] time and just heard it [Applause] it's just touching right there I'm going to zero the digital read out so now we kind of have a zero point where we know it touched and see as we go back across if it touches anywhere else wow starting to cut almost exactly the same spot as far as our reference on the bolt WS look at that that's more than nothing I mean as far as what it's touching there but okay what do you think and you can see how what you were talking about it with it possibly being CED out I don't know if that's from the way they well I guess they were cutting this way it looks like so yeah there I was expecting there to be a little bit of a dip across the middle here um so I don't know what do you think drop it down 2,000 see what happens 2,000 just to see so I'll just run to minus two on the drro and then I go I go past and then go back up just to take any backlash out on our machine and we'll just run it full speed here since that's kind of our first cut let her eat that's a PC cutter in there right now so it's specific po aluminum it's getting quieter Nick and quieter yeah it might mean it's starting to fall away [Laughter] already all right so let's see what our tooth out cut did okay we're clean over there and not clean wow how's that for flat makes you wonder how they even get these things to seal any guesses of how much we're going to have to Lop off of this I'm going to call I'm going to say seven though I think seven I think seven I'm hoping less but okay well two thou got there so I know five five I'm I'm calling seven let's see all right I'm I'm going to go straight to five straight to five sure 3, more yeah let's go let's do it Nick you know if you stand there for long enough you might have enough chips to recycle You' be able be able to pay me yeah I don't think I can afford you I didn't look I don't think it cleaned up what about you you think it cleaned up oh my if it didn't it's Clos oh my sneak to peek at least oo it did clean up oh well that's better than that's better than getting to seven and it didn't clean up I would rather I would rather take less off of this than more yeah so hey that's very pretty I mean there's a little a little bit of little bit ofoo just some paracity or something there well they're made of tin can so it's pretty standard how do you feel about that finish it's perfect okay that'll work great say otherwise we could take a finish cut but no don't need to no we don't need to that'll work just fine okay well let's roll over to the other side see if we can yeah make it right okay cool looks good with the porting all right I'm a betting man I'm going to call 6000 6 thou you think I'm going to say six thou I'm going to I'm hoping it's my guns okay so five again I haven't zeroed anything on this side so redid the setup but I'm close there since we just got done talking about crashing machines I'm going to really double check everything before I turn anything on does this whole project turn you off on custom engines yet no I'm actually really enjoying it you heard it from the man himself he's having a good time good for him [Applause] just touch right there again I kind of know that that point is zero and the point about right here is zero just by running the dial indicator across there so I'm just going to call that our zero point to start with so I zeroed the Z I'm going to come back up a little bit here this one might be closer but we'll see so you see it just barely took a little bit right there when I touched touched off start with the to out cut again sure that sounds great remember the people come here for you not me come here for the cleaning guy oh yeah everyone wants to be the cleaning guy well it's touching but it doesn't sound like it's really eating like it did on the other one yeah the other side it' be interesting to see how screwed up this side is compared to the other yeah that's it fairly light cut I like the aluminum chips with the PCD they just it's like confetti mhm looks like it's snowing is snowing so I know you visit a lot of machine shops maybe not not as far as this one is most of the time but how do you feel about how's the trip been how do you feel about it uh I've been to many machine shops and this is not the furthest I've traveled to visit a machine shop and you run a tight ship this is a phenomenal machine shop thank you so good job I paid him to say that kind of kind of he uh no no that's the honest truth and it is a it's a good shop good deal appreciate that oh yeah I think it definitely it cut all the way across here or it is cutting all the way across but you can definitely see that end is not touching um and it was cutting heavier just now than it was in the middle so mhm we're probably not going to be able to see as much but it was off a little bit it's cutting very weird right now I don't understand what's happening um I suppose if we did just a little one thou pass we know what's going on but why did it get quiet did we finish cutting just there so we're actually going to find out what's happening just a little wow look at that 2000s oh look at that just a little bit just a touch right there between the ports it's amazing that people even get these things to seal when they're that far off from this yeah well the question is how much how much of it I mean I don't know how how many times this intake had been on and off but usually what I see with it being used in 30 plus years old more of it being off is because somebody got aggressive with the Sandpaper or you know a flap disc or yeah so now this thing I I I don't know I'll bet you this thing is one or two years old I think someone just went to town and uh unfortunately this poor guy ended up in the wrong hands but it's in the right hands this guy's here to the rescue we can make it right all right so one more pass yeah and intakes done so we've got this wrapped up so it took about four, on that side took five th on the other side got a nice finish here and a nice flat surface so you guys might have noticed in the video where I did the the uh valve reliefs in the block that leaves a pretty nasty sharp edge so he's just coming in here and kind of giving that a little bit of a radius softening up that edge so that there's no sharp edges left figured a steady hand should do that not me so now he's doing some deburring just to give it some nice edges so we don't cut ourselves you ever seen a pretty intake like that not since the last time I glass beeded one well this one has a little more than that done I see pretty intakes every day it's kind of your job so I don't have a job fair enough but yeah we've got I mean this thing looks a lot different than it did when it came in I'd say went through surfaced it uh one of the sides was pretty wonky right yeah I don't remember which side it was uh I could tell you it was that side we took uh 4 out 5 out 5 th off of that side we took four off of this side but it was a little almost unnecessary there was a shadow on both dividers but that was about it this was pretty straight yeah wasn't warped at all warped a mile on one side in every direction really couldn't tell you why the cleaning guy you glass beeded it glass beeded it when you guys got done messing with it you've in this engine you've kind of dropped in here and there you haven't been a huge part of doing it but you've I'm
