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.

Would Recommend

I think this product is a good one to buy.

My question relates to the correct spark plugs for these heads. I have Autolite 216 spark plugs. The "Thread Reach" appears to be much shorter than the thickness of the head (spark plug threads). Is there a "better" spark plug choice ? Specs. on this "Flattie", 1946 1/8" over bore, Isky 77-B cam,Offy heads and tripple manifold with super 97 carbs
