Offenhauser 1069-400 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.

These look great and even more so after painting. The threaded holes for the thermostat housings are too close together. I had to enlarge the holes slightly on the housing so they would fit. I also used studs instead of bolts to make it easier to hold the gasket in place and to prevent cross threading which is easy to do with the threaded holes too close together.

In response to Ed's question, John stated "The main thing to avoid fouling the plugs is to use the correct reach. Offy recommends CHAMPION SPK PLUG:39-53FHF." I cannot find this spark plug, and Champion has no listing for Flatheads anymore, can you double check this or provide a link, or even better: provide an Autolite or NGK equivalent? What is the correct length? I tried 1/2 reach and even that seems too short. Thanks in advance.
