Forgot to add, Phillpot, what cam did you use and did you make any change to the valves themselves?
Sorry for the delay..............Cam is a Piper KBV629270, designated "Fast Road", I went for the cheaper regrind rather than machined from a new blank.
Valves were given a bit of polishing up to remove the sharp angles between the seat area and valve face. Heads were by no means fully ported and polished but some of the biggest casting lumps were ground out.
Not mine (photo found on Google) but gives the idea, note sharp edges on valve on right compared to smoother profile on left
