Have you had the valve covers off? There might be a casting number under there that can help.

Oh nice! I’ll gave to pull off the valve covers and see if there’s any markings. What’s the difference between gt40, gt40p and gt40x heads

Gt40 have 3 vertical bars on the end of the head
gt40p have 4 bars and a different plug angle
gt40x are aluminum they have a FORD logo on them I think.

That stamping looks like something someone punched in later. There will be more original casted part numbers under the valve cover.

I think the stamping is just a Serial Number.

Is the stamping the same on both heads, with a -1 on one and a -2 on the other?
