Can anyone ID this head for me? It has no markings at all on it.

The guys at F.A.S.T might be able to help you ID the head. It looks like the combustion chamber is bigger than the stock head , that would lower the compresion. Don't know why it would be done that way , unless it was for an engine that was made to idle for long times. I think I understand it to be that way. Seems like I had an old police Harley that low compression heads to idle while writing a ticket. Makes a good story anyway!

Maybe larger chamber for domed pistons?

Look more closely at the photo of the combustion chamber. It is smaller than stock, the area over the piston is smaller, the area over the valves is flat, not a ramp to the piston like stock heads. The recessed spark plug holes indicate the area over the valves is tighter, needing the recess. This is a high compression head.

Looks like a "hemi". I'd be interrested to know how it runs. Ron W

there is a similar one listed on d-ebay right now although with a much higher compression ratio. I agree, some manufacturer seems to be reaching for a hemi effect here.

the one on the d-ebay is a cyclone brand

That is what I think. The combustion chamber is only 1/2 inch deep, where stock is like 1 1/4 inches.

The head is not for sale at this time. I would just like to know what I have. May want to use it.
I agree with 2manycars. the combustion chamber is only 1/2 inch deep, where stock B is about 1-1/4 inches.

The high compression heads I am used to seeing have NO combustion chamber above the piston. This has quite a large one. I would say with the deep flame propagation area where the plug goes and the piston relief it was designed for a Hemi style piston.

I just finished having the combustion chambers CC"d. Each chamber measures 168 CC's. The area over the valves is flat, 1/2" deep. The area in the combustion chamber is domed with the deepest point only 1/2 inch. The spark plug sits in a seperate chamber with the bottom of the electrode about 1/4 inch from the 3/8 inch diameter hole between the comb chamber and the spark plug chamber. I can't think of anything else that would help.
Thanks to those who tried.
