ok to plug ALL valve cover ports after ls6 valley cover ok, i know this has been beaten to death, i just have one question.
im installing the 04' ls6 valley cover (12577927), has pcv built into it,
and a catch can, running hoses from valley cover to can, and from can to throttle body.
no breathers on can or valve covers,
its a nitrous car, no boost. mild bolt ons.
my question is can i just plug all three valve cover ports????

I did mine like ls1howto.com.
Ls6 valley, plugged driver cover, and kept passenger cover to throttle.
Norris can from valley to intake
I would also like to delete the line from pass. Cover to throttle.

No you can't. You have to have a fresh air source for the crankcase....It should be routed>>>>TB to passenger valve cover (fresh air line), Valley to catch can, catch can to intake neck (vacuum source to pull vapors from the crankcase). The other valve cover ports (on the rear likely) need to be capped as they have been replaced by the valley.
