Front end setup (Drag Racing)

What's the best way to set up the front suspension on a drag car, using the the original suspension.
I already have the 6 cyl torsion bars on the front, and the suspension has all been rebuilt. I beleive the shocks are 90/10's but I'll have to double check.
The front suspension feels stiff, when pushing it down, or pulling it up by hand.
I need recomendations on how to get it loosened up for the best front end rise.
Hi I am new to FABO. I just started racing my 71 Demon. I had a similar problem an you. My car has 28 in tall front tires from MT. With car at ride height, the front end was dead stiff, with no reaction. After talking with Angelo Phillips, I checked my shocks (CE 90/10s) and they were bottomed out! They were too long even though were supposed to be for a body. I installed the CalTrak front shocks, are shorter by an inch. Now with frontend same ride height, it is loose, and lots of reaction.
Would never have thought to check that! Might want to check yours!
Chuck.
