Spring/Keeper interference with Rocker
Honestly, nothing in the pics stands out as a red flag to me.
Stock retainers, 901 springs, stock rockers....... that combo has been used countless times with zero problems.
The only thing I see that might be evidence of contact is the shiney area below the relief cut.
I can’t tell if that’s recent contact or if it was always like that.
Is there some corresponding witness marks on the spring/retainer?
