Just picked up a used Edelbrock Performer RPM 2 intake manifold and was wondering if it was worth it to install it with the stock heads and cam? I have a Steeda #19 cam waiting to be installed, but don't yet have heads, so I was holding off on that until I got heads (getting either AFRs or TWs). Now I know the lower intake is the biggest restriction on the intake track, so thats where my idea to install it now came from. Only have minor bolt ons right now...full exhaust (LTs, offroad x), pullies, SPEC clutch, pullies, cold air, smog delete, RPM Extender, and 03 Cobra wheels. Thanks.
