Ride height~ (back to front difference)

brought my truck to a local off-road shop to adjust my coilovers.
Both My back measure 40” from ground to fender. Front is 36 - 1/4” and 36 - 1/2”.
The tech said if I raise The front to be even with the back my truck would look nose high.
I am having trouble with rubbing on my 285 70 17’s. I am doing a CMC next week.
I have light racing UCA’s.. It looks like ADS left a lot of room for adjustment. The locking adjustment screws are only about 1” down from the top, there probably another 3” down they can go. ADS said for every inch up I want to raise, adjust the screw down half that amount.

I’m left not knowing wether or not to lift or leave it. The tech has not been real helpful or seemed that knowledgeable.
