Fresh filtered air into the valve cover, from either the Throttle body port or from the fresh air tube after the MAF.
Blank off any outlet ports on the rear of the valve covers.

Anywhere between the front of the throttle body blade and the MAF will do.
Ideally it should be air thats been "metered" by the MAF, since that same volume of air ends up in the intake manifold once it has swooped thru the valve covers and valley.

Just about all the engines made after about 2002 do not have an external PCV valve like the LS1 had.
LS2/LS3/LS6/LS7 all have a baffle arrangement under the valley cover and use that instead of an external valve.
