273 rocker arm adjustment

so i got the complete set of 273 valve train...these also only have one hole per rocker, and no banana grooves. Also looks as if they have the same galling marks that i have.

Looks like i am just going to have to drill holes and add banana grooves.

I have a nice big swing drill press at work, i can put the shaft in the vice and square it up and drill those holes pretty easy. i guess the hard part is deciding where to put the holes and what size holes.

The banana grooves i can make with a small abrasive wheel on a die grinder. the very bottom hole needs the banana grooves?

What about plugging/drilling holes in the rocker arms?

Once i get all the drilling done i can polish the arms and shafts to make them pretty smooth again.

What is the consensus on all this fine stuff.

Looks like i will just have to run those push rods from summit.

Thanks yall
