I am in need of a good used pair of 6.2 or 6.5 heads in or near North east PA. I was doing what I thought would just be a head gasket job on my '82 6.2 and it turns out both cyl. heads are cracked. I really don't want to shell out the cash for a new pair. Does anybody have any good used ones??? or maybe a whole motor that they want to get rid of?
