LS6 intake worth it?
Nope not worth it for you. You'll gain more from a tune than you will from the ls6 intake.
And like someone mentioned previously, has a larger plenum, which makes gain only in high rpm...
I'm not saying it's a bad mod, just not sure it's everything everyone on here has it cracked up to be.
Another argument demonstrating that dyno's are for tuning & not for proving or diss-proving single modifications.

2)Maybe, depends on what you buy.
3)Yes, as noted originally
4)I tune on the street w/ EFI live. Further, a dyno would prove nothing. Too many Dyno variables involved when trying to measure a single mod like rockers. I could do nothing to my car & pick up 8 to 9 HP on a different day on the same dyno.
Yes, the airflow increased after adding 1.8's to my mild cam. I can log airflow w/ EFI Live. IMO, 1.8 rockers are a good way to to help small cams when the owner doesn't want the hassle of doing a swap "for small or stock cams ONLY." The rockers don't have to cost $500 either.
I stand by my statement that an LS6 intake & properly installed 1.8 rockers will wake your car up w/ less hassle than a cam swap.
How much power will a RR and ls6 wake a car up?
Can't answer that. It depends on too many variables. I can say that it will increase power. Increased &/or less restricted airflow + greater valve lift = more air entering the combustion chamber. After tuning for the air increase, power is increased.
Here is an example of some mods & how my car benefitted: (As noted earlier, I can log airflow).
After adding a Weiand intake, heads, mild cam, 1.8 rockers, & 85mm TB my car moved 27% more air than when it had stock intake, cam, rockers, TB, long tubes, & true duals.
After then shortening the length of the cold air intake & adding an 85mm MAF, gained another 3% of airflow.
I carried it out a day before I did the swap and a day afterwards. When it got to about 3500 rpm I could feel it pulling harder, and it did better all the way to the redline. Down low I actually felt a little bit of a loss, but that is to be expected with the larger runners/volume of the intake. Its definately cheaper than a fast setup. I couldn't justify spendng 900 on a intake and another 300 on a tb. http://www.tpis.com/index.php?module=2_17_06
