774 head casting on ls1???? Just bought a crate motor that has prototype cast in a few places on it block number 12550592 with 774 heads never seen these before the engine has never been run its all brand new also has "WC" cast in numerous place on the heads/block... I was lucky enough to steal it for $600 but now I am wondering where it came from??? Anyone know anything about it or 774 heads?
