Ticking noise, 383, can't locate the source

It has great oil pressure and all the rockers have oil on them when I pull the cover.
I'm not sure if that answers the oil ok when running question.

Engine was done in 2012 by a local machine shop, dyno'd, and has been without issue.

I'll have to look up valve stem sweep and geometry to see how that is checked, new to me.

Below is the cam specs I was able to locate from when it was built.

I didn't want to run it with the cover off and get oil all over the place, but I'll do it for a short time to see what I can see.
I'll also shoot a longer video with it running with the cover on.

I thought if I shot a video of it running the comments would be, you're an idiot, that tells us nothing, pull the valve cover stupid!

When I did pull it, my brain went to the one of these things is not like the other mentality.
