Hi, Stuart!  Pushrods often get overlooked and can be reused in many cases.  I like to roll the original pushrods on a piece of flat glass to check for straightness.  Ends can wear, a concern of course...Replacing the pushrods as you have done is a fail-safe approach, and Melling remains a high quality engine parts source.  (I always use a Melling replacement oil pump, most often a High Volume design.  OEM Jeep oil pressure runs quite high, so a quality OEM replacement pump by Melling is plenty.
