Great insight pmrphil, everyone seems to be on the same path. I haven't broken down an engine in along time but I feel I can handle the head removal and possible gasket replacements. If it ends up being worst damage I will carry to an engine builder I know that has been building motors for drag racing for 35 years. I would like to look at converting to 4v and increasing hp over the 400 hp range. He says a head exchange and few other items and it came produce well over 400hp. Thanks again for the input!
