I’d rather have one hole. That’s all it needs to live the rocker at the shaft. Just banana groove it.
I’m not a big fan of adding oil leaks at the rockers. For what you are doing you’ll get all the oil you need for the rockers and valve stems and all that with the oil flying around in the rocker boxes.
If you had 340 pounds of spring load on the seat and you were trying to make power at 8500 then yeah, more oil on the springs and such would matter.
