I have an engine with WPC surface treatment on the rocker faces and cam lobes and cam bearing surfaces. It was reasonably priced and quick turnaround. There is less than 1000 miles on those parts, visually there is a very faint shadow on the cam lobes from break in, the shadow appears less than usual. The rocker faces show no wear. .
