high guys was looking into to getting a set of cast aluminum valve covers from katech and was wondering it looks like there is no PCV routing I have a 2000 WS6 and was wondering if I could use an LS6 valley cover and a catch can with a PCV valve in line right before entering intake manifold car has an LS6 intake

Your setup works but using the newer version of the LS6 valley cover you can omit the external PCV valve. As long as you are getting fresh air into the motor normally a line from the TB to the valve cover or breather on the valve cover then this will satisfy the requirement.

i cannot stress enough how important it is to look past the aesthetics of valve covers and make sure they have, or have ability to have fittings so that you can manage your crankcase airflow and or pcv system.

valve covers (on a wet sump car) with NO breathing provisions or way to mount any are only good to look at NOT mount to an engine.. there is no other way. so please consider it ahead of time!

Katech valve covers have no baffles inside.

Good point Jontall.
The Katech, like most aftermarket LS Valve covers don't have baffles.
