The only place I can find a reference to 5W-50 in the 2019 v2 manual is for track use for the 2.3 EcoBoost. That manual specifies 5W-30 for track events for the 5.0. Since your engine is probably nowhere near stock the Ford recommendation would not be correct anyhow but have you found a manual newer than v2?Ford recommends 5W50 use in our coyotes for racing, its in the manual actually.
