i have an Edelbrock RPM Air Gap Port exit dimensions: 1.14" x 1.95".

I'm also running Trick Flow Twisted Wedge Heads, i am not sure of the port dimensions.

My question is, which intake gasket should i use? i was using the Fel Pro 1205 before, will this work fine?

any help would be great, thanks.

 

I believe the same size gasket you were using before will be the correct size

 

well i bought heads and intake off this guy, and he said the intake was port matched to a fel pro 1205, he included a new set. but i sold the intake and bought the air gap, but used the gaskets anyway.

 

I'd continue using the 1205's then. Your new manifold is not matched to it so you should be fine. You could, while it's off, match port your manifold to the gaskets and maybe pick up a pony or 2 from it. Just a thought.
