What's in the Box

Info

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.

These aluminum heads carry slightly different torque values as compared to the cast. We have a chart from the Edelbrock heads that shows the common flathead torque values for studs and also bolts and the torque sequence. Care needs to be taken to do this in a 3 step process. For Offenhauser values you may want to contact them on their tech line.

The Offy heads for 49-53 Fords have (two) thicknesses at the bolt bosses. The thickness at the ‘lower’ bolts is app. 1-3/8”, the thickness at the ‘upper’ bolts is 2”. The heads for 38-48 have (one) thickness, app. 2” at each of the 24 bolt holes.

1) I would prefer the Offy head with .425 clearance; can you get that version?

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

To the best of our knowledge, the stock-length studs will work for these heads. The studs in our head-stud kits for this application are all 3-1/4" long.
