I was hoping someone could tell me if my Edelbrock preformer intake with rect ports, would work with oval ports heads? i already own the intake, want to upgrade the engine to aluminum heads and i'm thinking that rect. port heads will be to "big" for a chevy BB 402. i was looking at buying edelbrock performer heads oval port 2.19/1.88. any help or comments would be greatly appreciated. i know it has to lose some performance, but it's basically for weekends and show.
