Is gasket matching, or port matching worth it? Personally, I think so. I recently gasket matched the intake, cylinder heads, and exhaust headers on a 383 stroker and I have to say, I’m very happy with the result. The engine seems to run smoother throughout the RPM range. It also seems to pull a bit harder. I can’t say exactly how much power it was worth, but it did feel like an improvement over just bolting those parts together. I plan to do this to every engine I build going forward.
In this video I cover the tools and processes needed to perform a gasket match, or port match on your engine. This information will apply to any gasket matching situation no matter what the engine displacement or design. I hope you find the info helpful.

You cut out the reversion wall on your exhaust port I have done that but I hear it's a No-No
Very informative! A few weeks ago I practiced on a cheap, temporary exhaust manifold I had to install on my car until I buy headers. The part about practice on something that’s not critical is key to this! I now have an oil pump that the manufacturer suggests port matching the oil pan holes to the gasket to maximize scavenging, so that practice on my exhaust manifold was beneficial for this oil pump job.
Great video 👍🏻
Great Video!! I'm grateful that I found it! Thanks!!
Probably a dumb question but is a tune necessary after gasket matching or is it just flow
All the years I have worked on vehicles close to 40 I have always sent my heads to a professional machine shop. Even the current mechanic iam working with sends them out.
What gasket do i use for my edelbrock performer on iron eagle heads? there is a gap at the runners. Seems heads were milled before i got them.1970 350cu
You guys that are not going to pin / align the intake to heads….Eric did not say to leave the intake manifold ports a bit smaller than the head ports. The little step will not hurt flow. < because of flow direction.. and will be way better than the other way around.
Port matching would be the appropriate term.
Nice car!
I think you will gain north of 25hp… Also it will climb thru rpms easier and more efficiently which if you're trying to go fast is important. Good job
I'm curious as to what you'll understand with this question……..What makes the Gasket the Boss? Should we trust the Gasket maker, or the Engine Manufacture?
i am about to port match my aluminum head soon so this is good info friend … peace n love broski stay safe keep it rad and build on 💪
doing this is so satisfying, let it take a week lmao. gunna ask my buddies to let me practice😂😂
Do not do this to a set of high dollar cnc ported heads unless you have training and a flow bench, this is a good way to ruin a high dollar set of heads.
I did the same thing with my headers and currently doing all this and expecting big returns. Good video but what grit sand roll did you use?
What incredible advise Eric, thank you. Especially the practise method to familiarise yourself with the tool, that's just golden! Could I use a Dremel Tool for this?
Do you port match the coolant passage also? I have a #906 Vortec head and there is ALOT of material within my blued scribe mark. Intake gasket is out of a kit. "Problem solver gasket" i was told. Plain metal core with black rubberized molded gasket around port.
Dammmmmn Eric that money shot on the valve ports!!! Looks legit
What about newer engines that use o-rings?
I love you bearded magic metal man
Thanks Eric. This information is extremely helpful that I’m at the prep stage and still learning everything I can about porting and polishing.
who all remembers when Eric got the car lift?
Nice informative video Eric On Gasket Matching @EricTheCarGuy
Couldn't there be a different gasket match depending on the brand of gasket ?
Hey Eric, while were on gasket matching the heads for some performance gains, what about Indexing your spark plugs + Side gapping your spark plugs? That's another modification i made to my spark plugs and had a noticeable idle quality/acceleration/Potentially better MPG'S!
Hey Eric how come you can't just trim the gasket to fit the holes flush?
I love that Bill Burr mentions you on podcasts, you have saved me thousands on my sons 99 Acura. Thanks dude!
Bill blur sent me here….
Fascinating stuff
Bill Burr gave you a compliment on this week's Hot Boxin'
When will you begin the foxbody, since you got it as a donor car I’ve been waiting… had my 79 for 9 years now… saw your fairmont build along the way.. but I went LS.. how is the fairmont????
Hey Eric, Bill Burr just mentioned you on Mike Tyson's podcast. About an hour in. It was pretty funny
Please improve your video thumbnail template. Your thumbnails are super cramped and hardly readable + irritating to the eye. This might actually make your video views skyrocket as well.
Eric, Have a 03 Regal GS w/sunroof that opens but will not close. I'm looking for a wiring diagram to trouble shoot problem. Any suggestions U may have would really help, thank U in advance.
Thank you 🙏🏻
Sounds nice at end of vid specially when it catches second
Thanks Eric for the info. I've been watching your videos around the time you started and I have learned alot from your instructions. One of my favorite videos is the 5 series on the Chevy SUV 5.3L engine swap back in 2011. I guess cause thats the same engine I had for a long time and I'm currently rebuilding a 5.3L in my 05 Silverado. Keep up the good work and thanks again!
