What heads are these???

The head in the auction weren't cast here. (They're just for sale here)
I went back to the phone pics my mate sent me from the foundry. There was a huge pile of many different heads stacked on a pallet. I couldn't see any markings on them though.

That was my first thought........but I am not familiar of any boats using S.B. MoPars. Very odd.

Correct Craft Barracuda and others.
