Message	I went from stock valves to 1 mm over with some portwork to unshroud the valves and reshape the runners especially on the exhaust side and i gained flow thru the entire lift range. I bolted these heads on to 88 mm block and see a power increase across the board. I used no math, instead i got some good advice from an experience engine builder and i tested everything on the same flow bench. Maybe old school but it worked. Harry Formerly yellowzxtt
