Help Please! Sagging Front end, can't adjust Ride Height at all.

I have read this, but is this just what was done in the past to get the cars to hook? I have no issue there hooking between 1.29 and 1.32 60'. It also does a decent wheelie, so I don't want to smash an oil pan on the way down?
It seems the car is set up and hooking well. Was this with the 1.03 or the 0.980? I am curious to see if those times slow down if you had the smaller bars during this time.
