No, I do not know what caused the scoring. The roller rocker was in good condition. The associated rocker is on the right side in this photograph; it is the exhaust lobe rocker.
I did not notice any valve recession of the exhaust valves. Perhaps it required 16,000 miles for my exhaust valve clearances to settle because of the wear on the camshaft exhaust lobe.
