Metal in oil

yes 17,000 total miles on crate motor.
I’m second owner since build, it had 10,000 miles on it when I purchased it.
I changed oil promptly and switched to Amsoil Z-Rod — PO was using Driven with Zinc. And did a proper break in. He’s on FABO as “ Cuda 36” and documented the build in “ restorations” … car was a SOCAL slant6
At that time I also added magnetic oil plug
Pics show last 2 oil changes, Nov of 23 and Nov of 24 each with just over 2500 miles.
Car never sits long … I drive it 7 days a week except in winter where it may sit like a couple of weeks to a month due to snow.
Hope this helps.
I mean should I have the cam pulled and investigate?
I’m not a guy that can do that work, although I do a lot just not internals —— I’m leaning that way.
I’m festitous on Oil Level
Shouldn’t be diluted
Does it have stock paddle style rockers and valve gear? I'd snatch a valve cover and make sure the rockers and rocker shafts are installed correctly and all the spacers on the shaft bolts are in the correct places. I've seen incorrectly installed rocker assemblies get chewed up on the sides before. That's one possible source.
