A good used part is the fastest and easiest way to go in situations like this, as long as the used cam does not have excessive wear. Some motors eat cams and some don't, this one doesn't. It's a roller cam.

It will also be obvious if the surface hardening is worn through - it will be a different color in that area, with kind of a "halo" around it. Absent any of that, you're probably good to go.

Thanks. That's pretty much what I was thinking and since starting this thread, I looked at and felt the undamaged lobes on my cam that look similar. They feel fine. When a cam actually gets eaten through the hardening, it's a pretty obvious and nasty damage, (which I've seen photos of).
Called a dealer to price a new cam while I was ordering some other stuff, it's NLA. So any aftermarket ones are probably China? Or do you think they still make them here? Anyways, I'll take the part made by Canadians in the mid-'90s any day of the week over a 3rd world part, assuming the used part is sound, of course. 😺👍
