Help me sort my combo

I don't see anything wrong with that cam but it could be worn a small amount and not be visible in a picture. Only takes a few minutes to check lobe lift if you have a lifter and a dial indicator. If the cam lobe is worn down then the engine needs to come out for a rebuild since that cast iron dust is now floating around inside the engine. I'd double check the cam for wear before I rebuilt the engine, especially when the cam doesn't appear to be bad.
