Need a little rocker arm help

Had a set of rockers that looked identical to those, and they were PRW rockers, and they were crap! barely oiled and had the same wear on the side of the rocker as you show. Mine didnt heat up like yours though. Take a look at your valve stems, mine werent oiling there and made little wear marks on the stems, needless to say those rockers are still sitting on my shop floor and will never touch one of my engines again.

So I yanked those off and put on a set of comp cams ultra pro magnums, should have spent the money the first time. Have a bout 700 miles on them with a pretty big solid roller cam. Lash has never changed and they show zero wear and oil really good. Worth it completely.

Also check your clearance for the pushrod holes, it looks like they were rubbing on the heads.
