torsion bar system, i need help

Doesn't the car also require a front end wheel alignment afterwards once the torsion bars have been disturbed or adjusted.

It depends on how close you can get the ride height to it's original state. I'd measure my suspension height before removing the adjuster bolts so I know where to set the height when finished. If the car feels good and there's no noticeable wear on the tires, I wouldn't worry about spending the money to get it aligned. Once the upper control arm and tie rods are touched, I take it in for an alignment no matter what.
