Intake won't bolt on!
So, I pulled the intake and cleaned all the surfaces. The gaskets tore so I'll have to get some new ones. Here is a picture of the intake on the engine without the gasket and it still seems a little off.
I measured the difference between the two intakes flange to flange and it seems the old one is 2/16 narrower than the RPM Air Gap so I assume the heads were milled to up compression. Guess I'll have to take it to a machine shop.
Intake was bought at summit racing and is brand new.
