Chris, you have to find 'balance' between push rod stiffness and the valve spring controlling your valve. When you have balance, you will eliminate 99.9% of your rocker arm failures. The event that causes rocker arm destruction is the 15 to twenty thousandths valve bounce off the seat. Each valvetrain will be somewhat different due to the weight of the valve(s). BTW, the weight of a push rod has to exceed 1.25 POUNDS before it shows a negative effect on the spintron(from a great NASCAR engine builder).

Tell your folks Hi, from Lynn and I and I hope you are all well.
