Wheels/tires or 500whp??

On higher lift cams for daily driveable vehicles in order to maintane "no float" with the giant intake valves on the LS3, it is preferred(although considered conservative) to replace the vavle springs every ~10k miles or so. Again, this conservative, but $300 every 10k miles as apposed to a new motor from a worn valve spring that let a valve float sounds like a pretty good trade off for me.

Would stiffer, aftermarket valve springs not help with that?
