It's all the EPA's fault. Removal of ZDDP from engine oil, and removal of the chemical that made the material hardness of the lifter/cam components. Lifter/cam failure was rare before those things changed. If I were building/rebuilding and replacing those components I would seriously check into cryotempering to make them as durable as possible.
