Help with UCA angles

I installed fox 2.0 coilovers and maxtrac spindles, i adjusted the coilovers down to about 1 1/2 inch of height and the angles of my UCAs aren't terrible but here's a pic. I can fit my whole hand through but would uniball boxed uppers take care of this to where I get some travel back?

The only way to get the travel back is to put a true lift kit on the truck and drop those coils down to a stock setting.

A uniball upper will indeed give him more travel. The issue with leveling kits/coilovers isn't that you lose travel its that you change where the wheel normally sits in the suspensions range. You will now have more up travel and less down travel. A uniball upper will give him about an extra inch of down travel.
