my 5.3 had 145k miles when I tore it down and the cam bearings had nearly double that much copper showing, so yes.
the copper is normal, from what I've been told you don't need to change them.

A lot of these Ls cam bearings show copper for whatever reason. The only way to tell if the bearing is out of spec is to measure it. I've seen pics on here of bearings in way worse shape!
