Replace rocker shafts for sure
High Dollar T&D offset rockers..SAME 7/8 od bearing in the rocker, but a reduced diameter shaft hardened shaft to take the 3/4 ID INM bearings so the rockers were not reduced to take the bearing, the shaft was.

Yep.
I'm reading contrary in some other responses...
One day it's fine to grind the rockers the next it's bad. Lol okay.
Must have learned something since then.lmao
The bearing doesn't make the rocker weaker in such a way that it will break.
I've used them too. Thick wall induction hardened shafts are necessary.
Can anyone show a pic of their rocker body broken due to weakness from the roller bearing, probably not.
Another thing, if you cut the stem height down for geometry, say you're stuffing a taller spring package in.. you can create an interference between the retainer and the rocker body on each side of the roller... it can also hit the spring recess if too large a o.d spring is used. Its takes some work combatting other issues to get there..but you can. It's sometimes give and take.
Those grooves are really wide apart huh... not typical.
OP should definitely rethink that whole valve train and get a geometry kit if you wanna use a big spring so you can raise and more the rocker back some.
