I am looking into porting and polishing my heads, and putting new cams in my car. I have a 2002 gt. I wanted to maybe purchase aftermarket heads but there arent many companys that ive seen that produce them for my car. I wanted trick flow but they dont make one. anyways what my question would be is what should i do to gain most horsepower. Example..... what type of cams, rocker arms, or valves....... If you have experience with this on my car or just know some good products i would appreciate your response
