Is this pcv set correct?
Also don't some guys disconnect the line going from the throttle body to the valve cover?
to be honest i am not sure if that is correct maybe someone else can chime in.
Also you can do a search for LS6 Valley Plate or Catch Can under Generation III External Engine
I did the LS6 valley plate conversion last month and used the ls1howto.com sites guidlines for runing the PCV system. I then installed the can as the manufacturer stated to.

You need a filtered fresh air source. I believe that if you run a breather on the valve cover, you can delete the line from the TB (more common in FI applications).
