That's nice for you, but in my world they suck..
If I had to guess, I'd say your bush material is different to what is used in the PRW's.
I don't wipe out rockers like mopar65's either.
I've never used PRW rockers, maybe they suck as well.
I've used the earlier Comp Cams rockers without the bushing, (steel on steel, prone to galling ) and with the correct oiling they looked a lot better than those PRWs pictured earlier.
Personally I'd be adding an oil groove to the shaft.
