454 BBC heads by FoMoCo??
Im gathering parts for a 454 build Im planning right now.
I was given these 454 heads by an old guy Im good friends with. They came off of a Marine 454 (a crusader I think). It was a Higher output 454 rated at 400hp, where as the typical marine 454 is rated at 330hp.
The guy needed new valve guides and put swapped these out for some new GM factory.
I was looking these heads over trying to get the casting numbers off of them. Well I haven't been able to match the numbers up to anything off of the internet, and whats wierd is they are stamped with FoMoCo? is that as in Ford motor company?
Heres the numbers off of them
