I am going to be in the market for gt40 heads as well as intake and need some help from you guys. First I think my goal will be the regular gt40 so that I have more header options. Intake will probably be the explorer variety. My first question is cost. I really have no idea what I should expect to pay so any guidance would be great. Assume a set of heads that is ready to bolt on, and an intake in the same condition. What is the going fare ebay rate, or classified rate for both.
Also, is this a worthwhile upgrade for an all stock 91 coupe? I will also add long tube headers and some type of off-road mid pipe. I know gt40's are better than the E7 heads from reading the boards, but am not sure if bolting them on with the factory cam will yield good gains.
Thanks for the advice.
