Reply to "How to match my intake manifold DOAE-9425-L with my carburetor ref.4777-7, 4150, cfm650 HOLLEY ?"

Larry thank you, in fact I do not wish to keep the EGR anti pollution system, the fact to increase the 2 bores diameter 38.5 mm to 42 mm like the other 2 bores, on my DOAE-9425-L intake manifold to get my carburetor, will perhaps bring a little extra HP breath to the engine ? Should I put a thermal insulating plate with a thickness of 5 mm between the carb. / intake ?
