Billet valve covers for LS3/L92. What do I need on them?

[scherp69]

I'm looking at getting a set of billet valve covers for my L92 (possibly LS3, still haven't decided if keeping the VVT) and I'm just wondering what I need them to have on them. I know that sounds like a stupid question, but I'm new to the whole LS thing. One set I'm looking at is the Billet Specialties ones http://www.billetspecialties.com/ite...d=240&pid=1017 or the ones from Eddie Motorsports. I see that they include oil caps, but don't have a PCV hole. Do I need one for the LS motors? I'm used the SBC covers. Does anyone have any other recommendations for LS billet valve covers? Thanks in advance.
