Super Stock Springs...do they make that much of a difference

I've been talking to Bob Mazzolini racing. I purchased the 3" inboard kit for the B/E bodies and am planning on using 456/457 B-body springs. I'm told that they work better than SS springs and are much more streetable when needed (especially vs. A-body SS springs). You may want to look them up and give Jason a call there. They are located in Riverside, CA and run EVERY Mopar setup that you can think of. Actually Bob himself just won Mopars at the Strip in his class with a stinkin' 318!!!! These guys are pretty sharp so you may want to do some research there before throwing good money after bad.
Just a thought.
Take care and awesome site!!
