The Ford Barn - View Single Post - What kind of heads are these

I was told by a circle track guy from the 40s they flipped heads on the early 21 bolts using a 37 front water pump block and early heads. Flow was better. Had to cut the firewall.

Seems someone flipped the heads on a 8ba. Wasn't sure you could? On the early blocks you can. How do the combustion chambers match up???

Maybe an advantage. Flow would be better for the block. Not sure I'd cut up a ford to see, less it fits.

2.8k seems like a lot for a unknown block, which is what it is. t5 conversion if with it would have some value. think someone thought they had a drag motor with the hei.
