3700 lbs.? for a 64 , I don't think so. I used 6 cylinder bars in my 64 BB car, no sagging. But anyway, do a inspection on the bushings, if all good,crank up the bolts some more .
it's ok to butt heads, just don't do it with a butthead

A coil spring will lose free length when it goes away. I would think a torsion bar would also not come back to it's original state. Been awhile since I've fooled with them, don't recall if the hexes are perfectly aligned when new and I don't have any laying around, but I would compare the alignment of the hexes with the alignment of a known good or new bar.
If you keep tightening and it keeps dropping, my guess would be that they are toast.

If the results don't match the theory, change the theory.

I had a 65 Coronet that kept sagging, found the anchor welds had cracked in the cross member. This allowed them to rotate, dropping the front end.
It may be ugly, but it sure is slow.

Also you can not adjust the front end and then measure with out moving the car so that it settles. usually you need to move it about 10 ft. unless you have plates to put the front end on then you can adjust to the height then it will stay there.

I jack car up let front hang turn adjuster set car down then bounce front end before I check my height. still have to roll it to make it settle. what is happening is when you raise it up the tires come in and there for it has to be rolled to make it settle. there is too much friction on the tire for it to spread out on the ground with out rolling it.

you still have to roll it to get it to settle down. what is happening is when you raise the front end up the tires come in and when you let it down they cant slip on the ground to spread out so you have to roll it to get it to settle. that's why slip plates work.
