Just to add a little info for those that may not.
You cannot successful regrind the pads on these rocker arms on a valve grinder attachment. There will be those that say they do and can but the geometry of the pad is not something that can be replicated on a Valve grinding attachment.
Common fault by doing it that way is, the adjuster swivel foot will stop lifting the valve and then slide across the Valve tip.
For those don't care, that way is good enough I guess, but for those that want it correct, ask who you have do this; do they have the geometry and does their tooling follow this geometry. Just because the pad looks good doesn't mean it will work correctly.
Add in poor cam profiles many copies of copies, then the wrong rocker geometry, you increase the hertz stresses and up goes the wear and down goes the possible performance.
Its all the little things that add up to more Torque.
