Here's my guess
Looks to me like an newer A12 (120Y) round-port head ground out to oval shape
Larger valves fitted, but the seats are not a 3-angle valve job like the original Datsun machining (which helps flow at lower speeds). Notched for larger valves too, so if you put it in an A12, maybe should notch the cylinder bores too. Might be a nice head for running over 4000 RPM frequently. Below that probably make less power than a stock head
Won't fit a 1200 engine unless modified for the oil passage. Will fit 120Y engines or A14/A15 engines
