Magnum Cam Bearing Bores Scored

I removed the cam bearings out of a budget 5.9 build I am planning and noticed on the #1 cam bearing bore, there is scoring (gouges) that appear to have been there for some time. The gouges are dark and did not appear like "fresh clean metal". The cam bearings came out relatively easily and these gouges could have been there since installation from the factory. Is this anything I need to address or can I go ahead and drive the new bearings in? They do catch a fingernail and there are quite a few around the entire bore. Photos forthcoming.
