But back to your original question yes you would need new torsion keys to get a 3" crank up front

I've never met anyone that did. The only exception is if the torsion bars themselves are worn out.

The stock keys will crank to the droop stops, at that point, the suspension is already maxed out. Aftermarket keys have no way to go any higher than the stocks.
