I have Caltracs on two of my Fairlanes and don't recall ever experiencing wheel hop with them, regardless of spring type. One pulls the wheels hard, runs 9s. Both currently have Calvert mono-leafs, but no issues before changing out factory multi-leaf springs.
I always use a bit of preload, even if only as much as you can get by hand-tightening them when loaded. It might ride a bit stiffer, but it takes the slop out of the suspension.
Why in the world are you still running street BFGs? Dangerous with the power you're car is making and with the TKX. Swap them for a pair of M/T Street Radial R 275s and you'll find them to be a game changer. They will also last a remarkably long time so long as you don't do long smokey burnouts.
Did you remove the factory rubber isolators from your springs and mount the pad directly onto the spring? Also, pad must be braced at the back and should be using 1/2" U-bolts.
