LA 340 rocker arm wear

Hi guys, I am rebuilding my 1968 340. Can you please share your thoughts on the wear of my rocker arms?
By scratching over the surface with my fingernail I do not feel any transition in the area where the rocker arm shaft is. I am also curious to know how to identify if the wear at the push rod location is still ok.
Here are pics of the worst rocker arm.
Thx!
Chris
