I typically run a ls6 valley cover to a vacuum source with breathers on both valve covers. a boosted engine combo could probably use a catch can between the LS6 valley cover and the vacuum source.
if you do not care about the environment, run a crank case vent to a 45* fitting on the exhaust collector. some claim to gain a tenth in the 1/8 putting that much vacuum on the crank case (seals rings better at high RPM) I don't see anyone on the truck side running that style setup, but there are a few over at tech that swear by it. never done it myself to verify the claims.
