Hence why i was askin what difference big valves would make!! So u reckon i'd be better off to stick with standard size??? I was lookin at gettin some stainless ones, 1mm oversized i think, would there be a negative effect if i was to get em fitted??? The head's bein pretty heavily ported, wanna try n make the engine rev, well as well as a cvh can lol!
