Ok ive been looking into many different options as far as heads go, ive thought about buying a set of used gt40 cobra heads and doing some serious porting, but then again ive heard afr 165's are the way to go. Im also worried about piston to valve clearance as i do not want to dig into the bottem end, ive also heard about big port jobs on the stock e7's, whats the best and most affordable???
