That's why I finally changed over to a flat tappet.
Jamo, why is a bronze gear required with a solid roller, I never did understand that? Isn't the oil pump driven from the bottom of the distributor such that any gear material can be used with the cam interface?

BTW, I went to a flat tappet also when I had the engine detuned.
