Roller Rockers

I have some flat spots on my roller rockers. Does anyone know what would cause this to happen?

Bad quality roller tips or not rolling.

Randy,

At one time didn't you do some testing on oil hole alignment with various brands? If so what are your recommendations?

All of them would work in their respective big block Ford stud valve trains but, those combinations of valve trains were vastly different from one another; a big block Ford valve train is even different from the exhaust side to the intake side within the same engine and requirements may be different. (valve tip height, stud angle, distance from stud to valve, valve lift, pushrod angle, etc).

There is no magic bullet of one which works well and others don't.
