LS2 build input - CAM/Heads

[SoCal_63 SS]

Alright, I'm stuck and would appreciate some input!!...

I've read a ton, talked with many, and am now looking for real world input and experience.

So here's the deal:
I have a mildly used 2008 LS2 from a Trailblazer SS (6700 miles). I plan to convert to a car accessory pully system in order to run a LS6 intake, Scoggin Dicky L92 CNC .650 heads, big CAM, LT Headers, 3.71 rear, 6 spd manual in a 63 Nova (2600lb car), etc.

My Requirements:
1. I want to build as much power possible but keep it streetable, ~2000 rpm power band start
2. No vacuum or other issues from the CAM being too big
3. Must have good lumpy sound (of course)

I'm looking at a couple differnt Scoggin Dickey CAMS (or other equivalant)
SS4 LSX Super Stick Camshaft 248/262 .614/.596 113
SS3 LSX Super Stick Camshaft 240/254 .609/.595 112
SS2 LSX Super Stick Camshaft 238/247 .640/.610 114
ST4 LS3/L92 Street Thumper 232/246 .595/.614 115

Is anyone running something similar in a LS motor?
What kind of power are you putting up?
How is drivability?
Is there another reason I should go big (valve train, etc.)

Any input would be great!!
