Default Rocker tip wear?

So I pulled my engine apart to do the lifters and when my dad came out and looked at everything he noticed the rockers are wearing on the tips, like alot. I had some stock rockers that I didnt use and you can really see a difference, theres definitely material wearing away. Has anyone else had this issue?

I have the isky triple 12 212/212 112 lsa .561 lift and the isky springs stock48 recommended for the cam (cant remember what the number is)

I did some searching and one guy said basically any cam above .550 of lift will start messing up a stock valvetrain but plenty of guys run stock rockers....

The only thing that could be it is I didnt check my pushrod length the first time, I just went with 7.4s cause thats what everyone else said, could too long pushrods cause this?

Are they contacting the middle of the valve stem? Is there a nice even wear line down the middle of the valves?

Eeek makes me curious how mine is - been spinning 6300 rpm for years with push rods that are little to long still. When I did my motor I was a newbie- didn't know to check or consider milled heads effect length-

You have a pic? I want to see

Have the heads had a valve job, or were the rockers not properly torqued down to the head? Do you have pics?

were all three of those out of the motor or only the one on the right? I'm asking b/c the one on the right has a different wear pattern.
The 2 on the left look like mine did around 110K when I swapped to my rollers

No the one on the right was from the junkyard head i got so its from a sfock motor

Well regardless the rockers dont matter because i bought harland sharps. So is this much wear normal? And my truck before I tore into it has 114k and i dont think my rockers looked like that
