Seems to me with a quarter million miles on it, the expeditious thing to do would be to replace the cam,lifters,pushrods and rocker arms. If one or two parts are worn beyond the valve train's ability to compensate for itself, the rest can't be too far behind. I'm sure that engine would have a steel roller camshaft as well. It probably wouldn't go flat and put shrapnel throughout everything, it probably would just wear down smoothly,but that and a new timing chain and gear set would probably set you right up.Who do you suppose has the record for the most miles on an original engine?
