Any adjustment of torsion bars result in change in camber and you should always do an alignment after installing components such as control arms to, including many other things, inhibit premature and unnecessary tire wear. Unless you wire up some pots to the the bolts on the torsion bar key bolts it is very difficult turn & tighten the torsion bars the same by counting rotations to obtain level ride height from driver side to pass side and and regardless you still have to measure from level/flat ground to the frame to properly set the ride height of the vehicle. If you really go protocol on this you adjust Tbars on the alignment rack and if I am wrong so are the ASE mechanics that do your alignment when you take a truck in.I think your method will increase tire wear. Also if you don't start out at the same place on both sides it will not be right if the measurement is the same.
