hey guys, i plan on making a trip to pick'n'pull in va pretty soon and if i happen to come upon some gt40 or gt40p heads/intake, what do you think theyd charge me based on your experience? also, how much would it cost me to have these heads rebuilt? and how hard is it to port and polish at home? i think if i can figure out how id just do the intake and not mess with the heads. Would i also need larger injectors (or just steal them off an explorer ie 22lbs injectors on em ) Thanks alot guys!!
