What happen to aftermarket cams?
 

I have a set of Web cams 505's that where previously installed in my motor. Im rebuilding the motor and im at the point to install the cams but im a little concerned. The cam tips are shiny, and some chipping on the side of the lobes. from my understanding Web welds and regrinds the cams? Is it possible the shiny at the tip maybe due to the dissimilar weld/casting metals? My brother seems to think that there may have been lots of valve float and the bucket was only making contact with the cam at the tip? Per webs cams website these cams can be used with stock valve train. Should i just run them or pitch them? Im going to email Web to get there opinion but i figured i would ask her first. What could have caused this?
