Here's another shot showing the valves.
A12 inlet valve 35mm but A14 exhaust 30mm?

These are sizes for A14 1981-1982 USA heads:
Intake: 35mm
Exhaust: 30mm

But the head here isn't a 1981-1982 USA head. Those have a different combustion chamber shape. And are oval port.

This head is round port:


I wonder if somebody just fitted larger exhaust valves to an A12 head?
