To answer your questions we would need to know if they are rules to go by.. The spring persay are junk... Instant things to help boost HP... Correctly rejet carb,, advance the ignition timing, install better springs, if its a hemi then change the head gasket down to a .009 thickness instead of the .040-.045 OEM one... With all said you might spend 15 bucks. BUT all of which may very well violate a rule pack..

Theres still things that can be done and shouldn't has issues.. Properly blueprinted carb,, needs to stay with SP brand carb.. Trick OEM valve springs and valves...
