Looks good! these engines usually live happy lives on a diet of Mineral 20W-50, but the 5W-50 Mobil 1 seems to work great!
The lead is probably mostly from being run on leaded gas.

My clothes smell like 15W-40 HDEO and 20W-50.

Potassium number is concerning. It may be part of the lead substitute package.

Cool car. How long have you owned it?

Is the 5 quarts of makeup oil due to leaks or usage?

Copper and Lead are way more than 2X the average!

I think you may need bearings really soon......

20W50 with chunks of Moly additives would help extending life, I suppose.
