What carb and intake for 5.9 Magnum?

Wideband is a wideband 02 sensor. Greatest thing since sliced bread for carb tuning.

Lift doesn't really have anything to do with idle or torque. Chop is in the duration and the lobe separation (pretty much). Torque is in the overlap (pretty much).

Also, you can't really compare duration numbers between hydraulic roller and hydraulic (not that you are doing that). A roller can remains streetable/easy on parts at a much higher duration than non-roller.
