is it ok to adjust torsion bars to change my cars stance.

think of it this way, when you put the car on jack stands, then raise the jack stands one notch, the car still weighs the same, it is higher but the weight on the jack stand hasn't changed, same thing happens when you raise or lower the torsion bars, you are not "twisting" the torsion bars, you are "rotating" them because they are moving the same amount front and back
