Yes. Absolutely got an idea. Look here first:

This WAS a brand new set of Crane Cams pushrods. After about 3000 miles of
running time disaster struck, big time. Witness one bent/broken intake
valve and one holed piston. Also notice the end piece inserts that came
loose from the Crane 3-piece tubular pushrods. Six of the eight pushrods
had the end pieces either fall out or were so loose that they could be
lifted out with finger force only.
Now thanks for reminding me, as I haven't settled this with Crane Cams yet.
