Offenhauser 1068-400 Details

These Offy flathead Ford heads are finned for high heat dissipation, bigger water capacity for "built" engines and everybody knows, nothing beats a full-dress flathead for beauty! Heads have a .400" valve relief.

3-5/16" bore, 4" stroke = 9:1 compression ratio
3-5/16" bore, 3 3/4" stroke = 8.6:1 compression ratio.

Did not know that I need to build spacers and longer studs to mount the oil filter because of the fins on the head.

I think this product is a good one to buy.
