you dont HAVE to have your head done,itwill run good with just the increase in cc.i have a 385 kit with stock sized valves it its just plain ignorant.im not gonna waste my hardearned cheese on a set of 1mm oversized valves that may only benefit me at 10k rpm.

have you ridden one with proper head work and im not just talking about oversizede valves im talking port polish and 3 or 5 angle valve job they do run a lot better with the head work

I'll only say it runs better if you consider an extra 15 hp or so to be worthwhile. If youre not racing a 350cc displacement class, dont bother. Go .080 over, port and polish, exhaust, carb, whatever and go have fun.

ya but he wants a 330 so it would be worth it

Just make sure your racing class allows over 300cc 4 strokes.
