Questionable Oil Analysts after new build...Thoughts?

Im probably just asking for more stress in my life by posting this. But wondering what other guys have seen as an oil analyst after a major rebuilt.

Motor is fully forged LS3 with approximately 2,600 miles on New motor. Had issues and bent 2 connecting rods. Professional Shop rebuilt motor with New Cam and all forged components and put my SLP Supercharger back on. During Break in was running 10w-30 VR1 Oil. Changed at 500 miles then 1000 miles. Then changed again at 1700 due to winter storage and changed it to full synthetic 0w-40 Mobil 1 Wix XP filter. Oil analyst was taken with about 2,600 miles on motor right before this winter storage from mid stream of drainage and the results are as below.

Blackstone labs reporting Higher volume that normal of Copper, Aluminum and Iron. Motor does have a mild piston slap when cold due to forged Pistons and clearanced cylinder walls, but goes away when warm.

Thoughts on this or too little miles to be a concern?

Sub'ing. Who did the motor build? Did you convey these results to them to get their opinion?

Iím in a catch 22 with that. After the build with the shop car was running lean with new motor. 13.1 AFR on dyno confirmed. So I ended up going to a different shop for a retune and fixed the lean issue. So I kinda made my own bed by leaving the other shop but I couldnít take the chance of blowing another motor and being out another 15k
