Just curious, What oil were you running with these rocker arms? Since the PRW Rockers are not rollerized, you need oil that has a really high Zinc content. I had the same problem with a set of the iron Isky rocker arms. Kept galling the rocker shaft up. Finally went to a hardened shaft and changed over to Valvoline racing oil which is the highest Zink content you can get now. Just a thought, but I would at least change the rocker shafts or you are going to experience the same thing again. Good Luck

Am I not thinking straight here? Those shafts look like the oiling holes are in-line with the bolt holes (???). I think the shafts I have worked with have all had the oiling holes straight down when bolted up (not aligned with boltholes). This is why there is a right and wrong way to have them installed.
I asked that question as well. If you look close, it appears there is a wear mark where the bolts go down thru down as well.
If those rockers he is using don't have bearings on them, then they aren't round because I would think there would be a wear pattern all the way across, not were it appears the bearings are riding, so I think the shafts aren't hard enough for those type of rockers.
But, never got an answer if both sides are the same or just the one side.
