Gentlemen,

I have spoken to all parties involved in my situation. This explanation seems to be the most logical conclusion.

Using the Dove rockers, Smith Brothers Push Rods, and Edlebrock heads you really have to pay close attention when marring these parts together. In my situation it has came to the conclusion that the rocker arm adjustment screw did not sit completely inside the cup of the push rod. This resulted in a broken cup on the push rod because all the pressure did not sit inside the cup but rather on the inside edge of the cup. Almost like trying to push a baseball into a coffee cup.

Solution/tip to look for:

Remove rockers and look at the bottom of the adjustment screw. If the motor has mileage you should see on the adjustment screw, solid silver impression where the push rod was making contact. If you see a silver ring with a black center, then the adjust screw is not make complete contact and can result in a broken cup on the push rod.

1. Take the adjustment screw out of the rocker and place on the end of a drill or lathe. Apply valve grinding compound to the tip of the screw and lap the push rod cup to the screw. Continue to do this until they it is seated completely.
2. Label the adjustment screw to that push rod.
3. Wash parts thoroughly and replace in motor.
