I have seen members do the ls6 pcv conversion and they still got oil in the intake. I have seen a catch can do the job time and time again. Save $ and just do the catch can. There is actually a thread on here about this same question and the ls6 conversion still had oil flowing thru.

Do both. I did the valley swap when I did my h/c swap also added a cheap( but looks and works great) catch can. IMO you can go cheap on the catch can if you do the ls6 valley swap too

If you do the LS6 valley cover I'd suggest putting a barbed T or Y in the fresh-air line, then connect a length of 3/8" oil/fuel line hose to the driver side valve cover rear port and use it for an additional fresh-air inlet. Then you'll be pulling fresh air into both sides of the engine(not just the passenger side) and pulling more combustion chamber by-products out of the engine at the ls6 PCV port. This is almost exactly I finally plumbed mine just the other day, except I used -AN fitting off the throttle body and I have GMPP valve covers with my ports up front.
