KobraKarl:
I will check when I get home Friday. I'm out of town at the moment. I believe that they were machined but I'm not fully sure.
My guess is a marine or truck head. Just can't reference the number.
Good to hear from another Contemporary owner.
Perry:
I'll post a picture and some dimensions on the weekend when I get home, but I am very sure it isn't rrae or valuable. Doesn't fit with the people that built it or my history with the car builder. More than likely I was ripped off and they are very poor heads from an old truck or boat!!!
