Ok so I'm in search of some heads for a 95 gt (prob used, shucks) but anyway here's the issues I'm wondering about: I realize its recommended to clay up and check ptv clearance before install. So what, does a guy take a gamble and order set, take them to a mechanic "clay them up" and hope there's no issues? Another question/concern I have is with selecting the correct pushrods. So what am I supposed to do go to a shop have em tear the motor down measure for length and leave it sitting in the shop torn apart until the correct pushrods come in from the interweb? Isn't there a set of heads out there that will bolt on and go? I'm looking to replace a fresh set of e7's that are on a fresh bottom end. I'd like to reuse my rockers if possible.
