Hey guys, I have a set of 906 heads and 2.14/1.81 valves. They are at the machine shop but I am going back and forth with the shop owner about the valve job. I want a steep 75 degree throat cut on the intake but he is scared to cut them because of the bulge in the bowl for rocker oiling. He is afraid a 75 degree cut down from the valve seat will break through. Anything special to watch for or advice on what I should tell the machinist. He is a chevy guy and I'm getting aggravated.
