Metal in oil

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.
I’m not sure, and to be honest I wouldn’t know what I’m looking at —- or Maybe I would, but then what —- I’ve never worked engine internals
I’m probably gonna get it into a reputable engine rebuilder in Spokane and have him look at top end and possibly fix what the issue(s) are
I’ve got so much into other upgrades ( Suspension / Fuel / Exterior/ wiring) that I wanna get to bottom of this.
Car runs like a beast and is a blast but something doesn’t sit right with me about the Metal Fuzz on magnet, especially since it’s not a fresh motor at 17,000 miles
Lots of good responses here that give me a baseline knowledge to speak to with a rebuilder.
Hopefully they can do work with engine in car if not to extensive
