The last thought was to use only new rocker arms with new hard-welded cams (e.g. from WebCam or equivalent). Okay, let's take some new factory rockers and put about 10k miles on them. Now, let's compare them to new rockers.

My question:
Besides a companion pattern caused by rubbing with a particular cam lobe, what prevents this almost-new rocker from being used with a hard-welded cam? Is the surface hardness so thin that a new surface can't be reground to replicate that found on a new rocker?

Can a hardened surface be applied to a rocker arm that's compatible with a hard-welded cam? At $65 and change per rocker and shaft (new), that could buy a lot of heat treatment. 65 x 12 = almost $800. That's about the same price as a set of cams. Hate to throw things away needlessly. Any options here?
