PCV Question

[GeoffP]

My valve covers have a grommet for a PCV valve and I can't find any LS based engine that actually used one so I think it must be for a fitting not a PCV valve. Anyone have any input on proper PCV plumbing using a catch can (Like Norris Motorsports)? I'm getting close to having mine ready to run and want to be sure I have everything installed in advance of first start up to prevent any problems (not that no PCV will cause problems initial startup problems but want it done).

Thanks!
