So when I took the two heads to the machine shop Elson pulls me over and said that I was too young for this but he wanted me to see this anyway. Before he said it I said that is a nice 2f motor you got there. It's actually a 1979 2f motor completely rebuild 2 years ago. The original owner left it and never paid. If you guys are interested let me know. I know he has 1700 plus in it just in parts.
