SS springs & Caltracs

I just bought a narrowed 8 3/4 for my Valiant Drag car and the rear comes with SS springs and Caltracs. I have heard here that you should not use SS springs with the Caltracs. I have also heard here from guys that they have both and they work fine. What I want to know is what is the best case senario and not what just works fine.

(1) Should I use the Caltracs with my stock springs in my Valiant and put the SS springs on my street Duster or

(2) Use the SS springs on the Valiant with the Caltracs.
