I talked with the engine builder and he stated that the likelihood is it was not seated properly initially and bent gradually which would explain why it did not create a ruckus initially and lasted a while. I think I will replace the pushrods and make sure they all are seated and hold on the replacements. He indicated he had never seen a standard Ford FE rocker come apart and NASCAR runs this similar approach with non-adjustables.
