I am currently freshening up my engine Abby installing new bearings, gaskets, and seals. As I was getting ready to put the camshaft back in I noticed this blemish right on the end of the camshaft where the timing gear bolts on. It almost looks like an old fingerprint and is slightly pitted. The rest of the cam is fine. I would like to avoid buying a new camshaft. Any chance I can run this?

Does it catch when you drag a fingernail across it? Maybe polish it out with some emery cloth.

FWIW I would probably polish it & run it.

Cast cams sometime came with blemishes. It's on the cam bearing end and at the end of the cam, I would say it is fine to run.
If it ran when it came out, it will run when you put it back in.

Run a red scotch-brite pad over it to clean up the bearing surface. If it is raised enough to where you think it will catch on something, smooth it down with some 1000 grit sandpaper or emory cloth. The idea is to get rid of high or sharp edges, not to remove a bunch of material. Having a low non-contact point way out there on the edge isn't going to hurt anything, but if a high spot catches on the bearing you are going to have a bad time.
