I have a 1986 4+3 Vette that has the Edelbrock hi-flo kit and everything hypertech makes for this car I was looking into getting a cam for it and some heads.the heads I've been looking into are the nkb 200 heads with 64 cc Chambers I'll be replacing my cast iron ones and thought the compression incress would help .I've heard so many different cam ideas I'd like to keep it flat tappet in steed of roller due to cost .can I get the money sound out of the car ? I'd like to install headers but only ones I've found are from headmen and the reviews are not good . Please help
