The lift makes very little difference in the rubbing. The point of contact is the tires rubbing on the stabilizer bar when the steering is at full lock, and lifting the front end 2"-3" doesn't change this.

The problem lays in the fact that not all H2's are created equal when it comes to how far the tires will turn at full steering lock. There are variations in the the castings of the LCA's (lower control arms) and the spindle/steering knuckles used in various production runs on the GM assembly line. The steering stops are cast into these 2 parts and are not adjustable. This variation in the castings accounts for the fact that some H2 owners report that their stock OEM tires rub at full lock, while others mount 37's on their trucks and experience no rubbing at all.

If wider tires than 12.50's are mounted it really becomes a problem and they they can also rub on the inside of the fender well (usually on the rear of the well).

The real point of the torsion key lift is to level the truck out (the H2 has a fair rake to it... front is lower than the rear), and gain more ground clearance in the front.
