I have a line on 1986 2wd 3/4 ton. I plan on going to look at it tomorrow. Anyway he says it has a pretty straight body but it has a blown head gasket in 6.2 diesel. I really just want it for a cruiser but was curious as to how much would be involved in swapping it over to gas. Or what is the possibilty a head gasket could just be replaced? I don't know much about diesels so any help is appreciated.
