remove the tension on torsion bars

Hey Guys !

I am thinking of lowering the front end of my 68 Dart Gt and was reading the posts here - in order to lower the front end, I should turn the bolts on the torison bars counter clockwise to relieve the preassure and make the front end go down? I only want to drop the front about an inch or so. The car sits perfectly level now. Can someone confirm as I have never done this before!
Thanks Guys !!!
Mike
