I would suggest doing what Ghost mentioned earlier. Jack up and support the front of the vehicle w/ some jack stands to get the weight off the front wheels. Next, go under the truck and loosen the torsion bar bolts as far as you can without removing them completely. Then just put the truck back on the ground and go for a quick spin around the block. Re-measure your ground to fenderlip and see if there are any changes. If the front is too low, repeat and tighten the bolts until you get the front where you want it. This will be the only way to verify that your torsion bar keys are maxed out one way or the other. Let us know what you find.
