Chris, FWIW, a while back Lou Mondello told me that while some head work is
nice in the U20 (good for maybe a 5% power increase, IIRC) some really good
results can come from proper valve grinding - up to 15% increases I think he
claimed. The reason is that the ports on the 2000 are pretty big to begin
with, I guess. Obviously worth doing both while you're in there, IMO.
Cheers,
Steve
