I just pulled them out and they are all straight and the cup ends are looking good until I checked the ball end and they all have same flat spot, these don’t look good. I’m making a cam change going a couple sizes bigger and I was hoping that I could use them, but after seeing this I have my doubts now. Which brand or mfg are you using?
Thanks

Are they all like that?
 
RRR have you ever seen any like this before? I have never seen any pushrods with flat spots on the ball end.
 
I can guarantee you that I have pulled LOTS of those out of running engines. They are just fine
 
I really think that end...youre just looking at the machining of the ball?? How could that be wear? Its adjoining a hole!

Yes. Lots of them. The flat is ground so oil can get under it.
 
This is the lifter for that pushrod? Any idea what lifter mfg this could be from, look at the retaining clip in it, I have never seen one like this before.

Typical cheap azz wire retainer. That's an AMC style lifter that's made for pushrod oiling. That's pretty much what a lot the Mopar style lifters have gone to.

Sorry to say but this isn’t secured by wire, it’s an insert. I have never seen one like this.

I have a 3/8" set of Isky and another 3/8" set from Crower and both sets have the same flat spot. Both sets have served me well in multiple engines.
