The rockers don't look bad to me.  If the bearing has any up or down movement change the rocker. The cam lobe is certainly scratched.  The surfaces are very hard to scratch under normal conditions. What would cause that I can only guess.  Did you run without oil?  Did the engine need any shim adjustment?  What was the before and after clearance measurements?
