The scoring is pretty normal tbh, but anything you can feel with your finger nail is fucked basically.
If that is damage to the cam lobe itself, somethings damaged the case hardening of the cam lobe itself. Only way to fix it properly is to replace it mate, and it’s only going to get worse, not better. It could’ve even been caused by a sticking roller rocker. All it takes is a momentary stall to the roller, and the damage is done
I have seen damage like this on a cam before and it ran perfectly fine, just gave off a little knock every now and then, which when amplified under the cover sounded pretty horrific lol!
This is all based on if you can actually feel anything on the cam though, so best way forward is to confirm first.
