Since we have to standardize to ppm per 1,000 miles for these results to be put into perspective, this is a worrying report. 14ppm/1,000 miles of iron is extremely high. Here is another Ecoboost 3.5L UOA:
This OCI was with 5qt of Castrol Edge EP 5w30 and 1qt of Castrol Edge 0w40. My goal with the mix was to beef up the viscosity just a bit since this motor is known to thin down oils with dilution and high heat. Looks like it worked compared to my last run of Castrol 5w30 (First UOA).

He has 12ppm/6,100 miles; 2ppm/1,000 miles; 7x less iron per 1,000 miles than in this report.
Iron tracks with mileage, so at 6,000 miles your iron would have been 84ppm. 😬
I'm used to Ford using Alumisil (bi-metal) bearings, silicon is really high, but aluminum isn't, which would lead one to conclude it isn't bearing material. I also don't see enough lead/tin for it to be a tri-metal bearing to explain the copper, so that's likely coming from something else (chelation), but where is the question! Also, your metal particles didn't look like copper, though if they are big enough to see, they are too big for the UOA to see them. Silicon is probably coming from silicone sealant from your timing set job if I had to guess.
Zinc and Phos are insanely high! WOW. Like
@RDY4WAR I am surprised that phosphorous is higher than zinc. Unlike him however, I don't think this is a good report, lol. That's primarily based on what I previously noted about the iron.
