You can upgrade to a LS6 valley cover and remove the PCV system if you desire. But you'll most likely still need a catch can. Do a search on the LS6 valley cover, its a common mod.

I'd beg to differ with the No effect on tuning statement. We've had plenty of customers that don't properly maintain their breathers that they just had to have because the internet tells them it is some wonderful thing. A saturated breather will affect idle drastically- Setting the IAC and TB set screw and or TAC module on a fly by wire car are predicated on airflow being steady. A plugged up breather changes all of that. Unless your engine builder specifically states that you have to have one (big cube motor) the stock pcv system and later LS6 pcv systems are the way to go.
