Mopar super stock springs for my Duster

I have a new pair of P3690456 & P3690457 (3400 lb) springs laying here that I was planning to use in my street strip Duster build, but I’m starting to wonder if I should look into buying the 002-003 spring instead. In the last Duster we built we used the 002-003 springs and when I took it to the track it hooked up great, even though it had radial street tires on it. I’m on a tight budget and don’t have a lot of liquid cash, but I’m not sure the 3400lb spring will work the way I want it to.
