Another "best cam" thread? AAAAAAARRGHHHH!!!! 
You really ought to do a lot of research over on LS1tech.com. You can see dyno curves for different cam or head/cam combos. A good rule of thumb for low end power, is don't go too large. You need to keep your dynamic compression ratio from getting too low, and the bigger the cam gets, the lower it will go, thus hurting low end. With headers and stock LS6 heads, the good old TR224 is a great cam. I have a very similar cam in my head/cam car putting out 410whp, and the power band is nice and fat from down low. With your LS6 heads, you'd probably get close to 400whp with stock heads.
Also, how much lope are you willing to tolerate. Where you want the power to come in, and how much lope you are willing to accept will limit your choices on duration and LSA. Go post over in LS1tech with a detailed description on what you want the car to do and what idle/ride quality you want, and how much lope you are willing to tolerate, and you'll get a lot of responses; a few of them will be from some really smart guys who know what they are talking about. The rest will be from idiots who will tell you to get the biggest cam you can that will allow the car to idle.

Cam selection will determine how the car idles, how it drives in the city, where the power comes in, where the power band is and a few other things. It should be based on what you are seeking from a performance stand-point. If you have an automatic, it can require upgrades to the torque converter.
There is a good primer article over on Popular Hotrodding written by David Vizard, who also has a good book out on Chevy Valve Trains where he explains things very well. Here is the link to the Popular Hotrodding article, hopefully it will give you some things to consider in you choice of cam:
