I Think ! Your problem may stem from an improperly heat treated rocker shaft, and not overheating / lack of lubrication. If such is the case, it is probably an isolate ocourance, and a new engine would not suffer the same wear problem. I would have jumped on the chance to turn in the troubled mill for a new one, but that's just me !
if I understand your problem correctly, the rocker shaft is experiencing heavy wear from the rocker boss, but the rocker is not ?
