WIW X-Heads

I agree, it sounds like a decent price, but what are you intending on doing with them? If they are going on an engine that requires X heads to be correct, go for it. If not, you're going to a bunch of money tied up in used heads that could be better spent a set of better flowing heads. By the time you add exhaust seats, guides, seals, valves, springs, retainers and locks, you might as well buy a set of heads from a one of several people here that would be cheaper and probably flow better.
