Rocker Arm help

In the spirit of “backwoods mechanics” I will throw this out there for consideration. In lieu of taking the heads in to a shop and having the saddles cut the correct way, an in the field fix is to essentially “lap” the saddles to the shaft. Use adhesive backed sandpaper on the shafts, carefully lap the shaft to the saddles, back and forth, little at a time, check your work as you go only enough aluminum is removed and the shafts fit correctly, with a good radius. I know many are twitching, convulsing, shaking all over etc at the thought but.....it can be done. Just a little Patience
