So, I’m going to need to redo my head at some point in the future, and I’ll have it lightly ported and polished at that time. My question is regarding the valves. If it’s an easy (ish) swap, will I be able to use the stock size valves from the later S50B32? I know that the stems are a mm smaller, and the head size is a bit bigger - both good things.
I just haven't tracked down a 3.2 lower head for a reasonable price yet.
Thanks,

i'd wait for a complete b32 head the ports are better its not just the valves

Ok, thanks. Are the throttle bodies worth tracking down, too, or not too much gain from them?

Hard to say. They are 1mm larger in diameter. 6x .5mm larger radius.
But then I would also use the shorter B32 intake trumpets.
