Stainless, Bushed PRW Rocker Arms

Actually I do.
I kept on the b3 spacers Mike made for the PRW Rockers.
They helped to get the nose of the 273 Rockers more towards the center of the valve tip.
I talked with Mike about that he said that would help for sure.
The Geometry is probably not as good as with The PRW Rockers, but better then with No spacers.

Check the 273 shaft diameter and measure the bores of the PRW rockers. If you have .002-.003 clearance run the 273 shafts.

I don’t get why anyone thinks this is anything but an oiling issue. The bronze bushing is grabby. It need MORE OIL.

Groove the shafts or use your 273 shafts. The 273 rockers are grabbing the shafts because they are ductile IRON, UNBUSHED. If you bushed them and didn’t use a groove and VERIFY your clearance they’d grab the shaft too.

YOU DO NOT HAVE ENOUGH OIL AT THE SHAFT FOR BUSHED ROCKERS.
