I will have the Edelbrock Performer RPM Air Gap intake manifold (#7501) and a Holley 4150 700 CFM double pumper carb (#4778) on my motor. What gasket do I use between them? There are so many that say will fit the 4150 carb, but I don't know what size to get for this manifold. I assume I should get one with an open center, like for a single plane manifold, because this manifold has a big "slot" cut out in the middle, so it's almost a single plane. Correct? Any sizes or part numbers would be greatly appreciated. Thanks in advance.

 

Anyone?? Thanks.

 

I'd use the thin one with one big square hole.
