speed head

[Jim in S.C.]

Can someone tell me the compression ratio for a unmilled speed head? It has the numbers A6050B cast on it. I assume it was made 11-28-35 That is also cast on it.
Also anyone out there now useing this type head? Please say something good about it. Thanks

A picture of the head, and of the combustion chamber would help. Do a quick "cc" job on the head. I have a chart someplace, should get you close.

Good head to use if you bought it right. 5.2 comp ratio.
Just don't over heat it they are thin in the combustion chamber and crack easy.
Use a Model B Head gasket with it.
Best brand is the best one to use.

I have one. I had it on the roadster pickup, but saved it when I sold the truck.
