thanks all for the quick Feedback, this group is great.
A followup question.
I noticed that one of my pushrods seems to be a replacement. It is mostly clean compared to the other 11 rods, but in particular I noticed that the ball side towards the lifter was solid and did not have the small hole in it like the others. I recall from reading that the hole is there to help with oiling and lubrication, so my question now is, has this idea been updated with better quality materials for the rods and so the holes are no longer needed or made that way.
