too bad we can't see a pic. I think you are overly concerned about the rocker tips (not having seen them). You say these are stamped steel parts. Two pieces welded together. The rocker tip area at the valve would or should be hardened. Is there a separate wear pad welded there? Even if .030 had to dressed off that tip it would not affect geometry significantly. Don't forget the rocker ratio working in your favor to reduce the net affect at the pushrod. In fact, it could work to improve geometry. Any time you have a valve job the valves are set deeper in the head due to grinding the seats. Odds are unless the machinist made correction at the valve tip, the valve tips are taller in the head than they would be otherwise. They may even be at significantly different heights if the machinist has ignored this dimension. This would tip the rocker back toward the pushrod. Dressing the rocker tip would tend to tip it back the other way toward the valve. There is adjustment at the push rod.
I would not mill the pedistals. You just need to get those rocker tips smooth again with a contour similar to original. They don't need to be exactly the same say within .030. If you cannot dress them smooth and be comfortable with the result, they should be replaced. Just my opinion.
