Since most wanted their product to look like an original they didn't mark them. Some are known to be bad or marginal but without knowing the maker it's hard to know what you have.
The pinnacle of the A flathead has to be a Brierley. It's 7:1 with a thick deck and taller height to increase cooling. It also has a very efficient combustion chamber.

That's nice. Does Jim still sell his heads?
