273 rocker info please

hello FABO, my buddy Dave task me with identifying a tote loaded with different 273 rockers, I am going to use a set on my 340 build but not sure whats in the tote.
They have different numbers on them and i hope someone can shed some light on exactly what he has, i will post the numbers ...
Any info on these would be appreciated, is one set better than the other?

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.
