Pcv help

I'm trying to plumb in my new catch can and I also did a head swap and now have new valve covers- well the drivers side has the pcv valve in it at the back and the pass side one has the outlet to go to the tb. Do I only run 1 line from the 1 valve cover to my catch can and then intake

Or do I go from both valve covers to the catch can then to intake and then run the tb hose to a nipple on the oil filler cap

Or is the tb hose needed?

I do not nor will be getting a ls6 style valley cover.

The PCV routing goes from the back of the drivers side valve cover then y's off and one end connects to the back of the passengers valve cover and the other routes back around to the front of the intake manifold (attach your catch can to that last line that goes into the front of the intake manifold; insert it between the PCV valve and the manifold). The nipple at the front of the passengers valve cover goes to the throttle body. You can also insert a second catch can there if you would like, but primary should be the one going to the manifold.

Edit: I apologize I just read you have new valve covers I will try to dig up some routing schematics I found on ls1 tech a while back
