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.
