Hi guys. I have a head that i had in storage and i'm not actually sure what it is.

It does not have H89, H72 or H75 on it.

And it has smaller ports.

Although it has an open chamber, like the h72 & h75, although the H89 has a kidney shaped chamber.

And an a12 GX has a kidney shaped chamber also.

Could it be, that this head is a a14 GX head if there is such a thing?

Its in original condition, I have valves and springs in a box on their own also.
