273 rocker info please

Pick the best with the least wear on the tip and no galling in the bore. Locknuts are not required. Neither are bushed bores unless you are really winding that 340 up. Best shafts have 2 oiling holes per rocker and banana grooves on the bottom. Check the shafts for wear and clean the center bore well.
66fs, as im looking through this pile of rockers im noticing that the round area that the shaft rides on... on some it looks like a perfect circle and on others its a little bit of an egg shape, maybe its not an issue or maybe its an optical illusion lol... there is no galling on these , all look pretty good
