could i port out my d0oe 351w cylinder heads to match an intake manifold that has been port matched to a set of Edelbrock perf. RPM heads? and which intake gaskets would it use?
Use a Fel-Pro 1250 gasket.
I'm porting the same heads,get a good porting kit and a area free of stuff because your gonna get iron dust every were.You can enlarger the ports a lot but don't go into the pushrod holes.
