The reason I passed mine off as a headgasket right away was the guy I bought it from put a body lift in but didn't address the overheating issues. He overheated constantly ran it until it shut off on him. I told him over and over what he needed to do to fix it but he didn't think it would work. He thought there was bigger problems. Finally he got sick of overheating every 20 mins or so, so I bought it. It was fine for almost a week, I overheated once but didnt shut down. I fixed the problems and never overheated again. But I think the damage was done, that is a killer for headgaskets. Good way to warp your heads too. Headgaskets don't blow the exact same way everytime, sometimes there are odd problems but my problem as well as justbustins was a common well known gasket problem.
