Cylinder Head Porting and Port Matching

Anthony @ DIYautotech takes you through the steps on how to port match ( gasket match) your cylinder heads. This is a fairly simple project that may take you about a day, but will give you a cylinder head with high flow rates.
High Flow = More Power

forgive me for calling you an idiot, it was rude of me.

As to who I am, I have been it the automotive field for over 35 years, I started out turning wrenchs and the ran many many shops, and taught automotive technology for most of 15 years. I also was head of the engines department and taught airflow dynamics and performance. For what its worth I am also A.S.E. certified. Please feel free to contact me again.

@rgmathers This is not a pissing match my friend. Just showing folks how to do the basics at home.  When I am working on real performance stuff, this obviously isn't the route I would take, nor have I. I have built a couple 400+HP subaru wrx blocks & 2 dodge 440s, so I know a little about airflow dynamics. I'm no expert, but I try to help those out who know nothing of it. So please keep the rude comments away. Do us a favor and make a better video, instead of being rude.

@rgmathers and who are you exactly?

[staticxmako]

you sure its not just the gasket brand? or if you need a new gasket down the road and its from a different brand, willl this not be any good?

[DIYautotech]

@staticxmako All the brands of gaskets are going to produce a gasket that is the same size. They have to be "standardized" due to OEM and OE specifications. Aslong as you buy a product that is OE or OEM then you will be in great shape.

OE - original equipment

OEM - original equipment manufacturer

@rgmathers Takes a BIG man to admit he jumped the gun a bit, but doesn't detract from the message.

[rgmathers]

@gunforme I agree with much of what your saying. I don't Like to really open up the intake ports as it slows down air and velocity is what its about. I just smooth and blend, I have friends that re shape ports and such but that is above my skill level. It is so hard to explain all of this in just a few words. I agree, the smaller the intake port the better low end torque will be but as usual it all depends on what you want the engine to do.

[gunforme]

@rgmathers I agree on the importance of good intake airflow, but I'd encourage others not to underestimate the importance of the exhaust side. It is very important to be able to get the exhaust gases out quickly. When doing this kind of work I like to simply clean up and polish the intake ports, not really open the up. There smaller but smooth intake ports mean high air velocity=low end torque. The exhaust ports however being smaller usually benefit greatly from being opened up.

@DIYautotech I have purchased two different gaskets in the past and they were slightly different from each other. I had purchased one, I believe it was a Felpro, and I used it to gasket match a intake and cylinder head. Later when I went to do some work and change the gaskets I purchased another which was a little different and didn't match up quite the same. I took it back and got a different one of course. I believe that is why some choose to port match rather than gasket match.

2nd question , why match the cylinder head to the gasket ? when the gasket fails there is no garranty the next gasket will match exactly.

[wan2bvader]

1st question, why is Arnie Cunningham from the movie Christine teaching?

[s0lidllama]

My question is since youre removing such little bit of material like on the 2, 3, 4 holes (left to right of camera) is it really worth your time and effort?

[renetony29]

anybody else hear the breathing and moaning???

[rgmathers]

@RCMACSPEED yes I regard him in the same way, He has not only worked big bore engines but small as well, his mini actually beat an F1 car!! in the hill climb. he is located in tucsan AZ. I believe and he will answer any question anyone has. I have studied most of the great ones,Jenkins,unich,Landy,but david has always made the most sense to me in his approace to performance. by the way great suspension film very cool. seems you know your art well. I enjoy intellectual diversion.

[RCMACSPEED]

@rgmathers I read his book on the mini engine I think that guy is a genious maybe at different rpms their is a different aproach.
