As mentioned above try the phenolic spacer (3/4"). I think some manifolds have exhaust gasses routed through the manifold in the carb area and I think you can get plugs for the holes. I am going from memory on this so you may want to ask over in the "Engine & Drivetrain" forum to make sure my memory hasn't failed me....

Oh, and to the board.

I think you are right about the exhaust. I know my uninstalled edelbrock intake has a crossover for exhaust which is directly under the carb. An old hot rod trick (and something which was done to my intake before I bought it) is to close up 1 side of the crossover with epoxy and drill a hole to allow some air to pass through. I think it keeps the intake warm enough for street driven vehicles, but not too warm as boil fuel from the bowls.

check your gas cap for pressure buildup due to poor venting of the tank

Would pressure build up cause an issue or just vacuum from lack of venting?
