My worry is that I find little difference from one side of the cam lobe nose to the other side of the nose. The noses are shiny all of the way across. Isn't there supposed to be some angle built into the lobe to help spin the lifter or is all of that motion built into the lifter. It is my understanding the reason for the recent cam, lifter failure, is due to the improper machining of the lifter face profile more-so than the metallurgy. I have some decent looking old lifters.
