Yes, the balljoint flip will make the truck lower by 3/4 of an inch. Imagine that you put your truck up on jackstands. Now imagine your LCA not moving at all. Next imagine that you do a balljoint flip which makes the wheel/spindle move up into the wheel well (lowering the truck more). Now to make the truck ride at the same height as it was before, you tighten up the torsion bars to "raise" the truck back to the ride height it was before. BUT, the LCA will now be FURTHER away from the bump stop by 3/4 of an inch, making the ride more tolerable.
And yes, you'll need to cut the "hump" off the top of the LCA to do the balljoint flip.
