Is this a symptom of worn out torsion bars?

Guess I didn't make it clear initially. My bad. The original slant six is still in the car, as well as the original slant six bars. The question, I guess, now becomes how do I ensure that the torsion bars are installed properly?

I know the rear of the bar will seat into a fixed socket in the cross-member. To seat the front of the bar properly in the pivot shaft's hex socket, how should the adjuster be positioned (threaded in or out), and should the lower control arm be hanging freely (with upper bump block removed)? In other words, how do you know you aren't "off a tick" to begin the ride height adjustment?
