The shims will wear the alum pedestal, post #8? Don't think so.....
The original 1958/9 factory heads came with alum blocks pushed onto the shaft & acted as the hold-downs. No shims used, rockers in contact with the alum..& no wear. Not sure what year the alum blocks stopped.

Not sure if the PRW stainless rockers are the same as the CAT stainless rockers, but my CAT stainless rockers (1.7:1 ratio) the roller tips and adjusters did not seem to be hardened correctly and started wearing out with only a few hundred miles on them? The rocker bodies actually seemed pretty nice with good pattern on the valve tips, but everything else was junk. I might have them rebuilt with good roller tips and adjusters to try them again as the cost of rocker arms have gotten crazy expensive.
