speedmaster pce273.1050 5.011 x 1.60 x 11/32 , used them and their 2.02 intake several time to convert small valve j and other 360 heads to big valve . no issues , my machinist likes them
This customer wanted 2.055 valves so we went with Liberty Pro series valves. I just ordered another 550.00 worth of 1.60 exhaust valves, 2.055, 2.08, and LS valves.
