Well the stock spings are prety much maxed out. you will get to about .605 before you have PVC problems. But sense you dont want to change spings you are better off sticking with the stock cam. If you want a cam you have to get every thing that goes with it.

you can get a spring and retainer kit from SDPC for 175$ just get that and their adj. timing chain =80$ and get your cam and you'll be set.
its a JOB to put the springs on, but its well worth it when you hear that thing start up. springs take about 2 hours to put on ( the first time you do it )

The stock springs aren't worth keeping, even if you plan on keeping the stock camshaft! The factory springs are very light on the seat pressure. Anyone that is doing any kind of racing should at least swap out to the LS6 valve springs IMO. The '02+ LS6 valve springs are good up to .550" lift and are actually slightly cheaper than the '01 LS6 valve springs that are rated for .525" lift.
There's more to p-to-v clearance than just lift. The duration and aggressiveness of the ramp rates on the lobes play a large factor, too. We are currently running a cam package special for the month of April that includes a cam for just about every occasion.
