Looking at adding either Gregg Good,Roe, or a local shop ported heads to my 10lb supercharged 99 GTS. Car already dynoed at 630hp/670tq with my current mods (ballenger headers,hi flow cats,corsa catback,water ****, VEC 2, and 1.7 jesel rockers) How much gain do you think I will get from adding ported heads? Is it worth the $$?
