Anything to be concerned about “Oil Analysis “

I recently rebuilt my Lq4. I assembled it with AMSOIL assembly lube, and ran it for the first 100 miles on AMSOIL break in oil. I changed the oil over to 30 weight conventional oil, and ran it for 600 miles. I took the oil from the 600 mile oil change and sent it off for analysis. Here are the results. I’m no expert by any means. This is my first oil analysis. Do you guys see anything that might be concerning? Just making sure my rebuild is happy. I now currently have a little over 1000 miles total on the rebuild. Oil pressure is great. 50 cold idle, 40 hot. At wot I get 70-75 psi hot. Thanks for looking.

I'd be happy enough with it. Iron and chromium are your block/rings wearing in, and would be expected. The lead/tin/copper are low which is bearing wear and looks good.
