If you want some lope then you will want something with a little overlap to it. However, too much overlap will negatively affect driveability and emissions so that's another thing to keep in mind. Since you have the stock manifolds and h-pipe I would personally opt for something that has an appropriate intake and exhaust duration split that takes the exhaust restriction into account. I would speak with some known LS cam gurus to see what they can set you up with to achieve your goals. Some names that come to mind would be Ed Curtis at FTI, Martin Smallwood, Tony Mamo, Brian Tooley, Geoff at EPS, Pat G.

In addition to the cam you will also need/I would suggest considering:
-Valve springs (I would suggest a kit that includes retainers, locks, seals. Springs must be appropriate for selected camshaft)
-Pushrods (Must be appropriate length)
-Timing chain upgrade such as the LS2 chain (Not mandatory but a good idea. You will probably also need a dampener)
-Trunion upgrade kit for your stock rockers (Not mandatory but a good idea)
-UD pulley + belts (Not mandatory but something to consider while you are there)
-Dyno tune
-Gaskets
-Fluids
-LT Headers w/ X-Pipe (If you want to optimize the sound and power you get from the cam swap)

Hopefully I am not missing anything but that should give you a general idea.
