would you recommend it for a h/c ls1, im planning to rebuild the top end in mid dec. nd dnt want oil in my freshly cleaned up manifold lol nor do i want my to waste me a qrt of oil every 2 months
Unless you want to clean up the engine bay or the PCV hoses are worn I don't even see the point of the ls6 valley. A good CC like the RX performance or Saikou like mentioned above will stop ALL oil getting into the intake.

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.

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.
