The flat side of the roller rocker tunion was up for the poly lock. I can see how this could happen.
The arp studs are longer 1.75 compared to 1.5 for the stock... With shorter pushrods should bring the rocker lower on the stud.
I did wear check with a felt marker on a few location and it looked ok.....
Next will be stock legnth.
Most of the wear marks are centered. But some are on the sides. Just from researching Pro comp heads on different forums there are reports that the pushrod guides are off and the studs are off centered too.(cheap machining in china) Looking at the guides you can see it. Isky make a adjustable guides I will try. The rockers look in good shape with no stress marks.
thanks again for the thoughts.
