Help to ID these roller rockers and problem...

[Bad Bowtie]

Couple of things come to mind on the 4 questionable rockers. Due to unknown rocker mfg (more than likely china) could it be possible that when they assemble the rockers they are picking from hundreds of trunnions that might not be designed/machined the same. It seems to me that i have seen rockers before with this same recess. Also if it was "eating away" that .030 wouldn't that metal have taken out the trunnion bearing or at least made it harder to pivot on. This is interesting. Better off with Comp rockers anyway.
Let us know if you come up with anything new

I agree. Some trunnions have the recess machined and some don't, and those with the recess look too uniform to have been chewed up that way. They look like they were made with the recess and it's sort of a mixed set of rockers.
