I am referring to the port diameter at the intake manifold not the valve
size. I think the valves are the same on the standard and Holbay heads.

Huh? That doesn't seem right. How does the head breath with an intake
only, what, 1.2"? I can't recall the stock size, I seem to recall
about 1.4" for the intake & 1.2" for the exaust.
