What would cause this weird bearing wear?

So there are a few issues that I know of. One of those is there was constantly little pieces of copper in the oil, slowed down as I changed the oil, but I figured it out once I took the heads off. It goes back to the issues with ootb eddy heads, the springs gouged into the little copper shim under the spring that should have been a hardened cup or something, one bearing actually had some pieces of crap on them and stuck in the tangs, not going to blame the heads completely though, Im not sure where the rest of the crap came from, thought I was really clean when I put it together.

All this happened after the line hone, and the motor is a 360 with about 3k miles on it, I know with that little miles the bearings should NOT look like that. I looked more into it and I dont actually think that my crank was even polished, I looked at my receipts and found nothing for that, but it was really nice when I got it (I thought), and I doubt it was done for free lol

The bearings could be too tight, I have no idea how that happened there though, I measured with plastigauge, but mustn't have done something right (first time ever using it).

When I put it together I just used engine oil, and before I started it I primed the oil pump. I wasn't aware that I needed to coat the bearings with more than that. Would cleaning the hell out of the block/crank, using the right assembly lube and ensuring that the bearing clearance is enough after the crank was turned fix the issue?

Thought I was really careful with this build, I guess not though, was my first time building a motor.

Now just to remind you guys the third picture is NOT mine, only the first two are, I just used that picture I found to easier see the wear pattern that I am talking about.

Seems like your crank was not balanced correctely, if it was mine the firrst person id roust would be whoever machined it all, sanity check with them and your receipts make sure something like that wasent overlooked. All you can do is retrace your steps, mesure, and cross your fingers. Best of luck
