Location for oil holes on rocker arms?

You did mention it, and there were comments about how there “needed” to be a hole on the spring side.
I knew there were no holes on the HS rockers, which I why I asked the question.
To let people connect the dots........ that maybe a bunch of oil going to the valve side may not be necessary after all.

There is no direct oiling to the bearings or roller tip on most Jesel rockers either.
