I assume that you decided on the ls6 valley cover because it does a better job of not allowing oil to pass through (compared the the orifice in the passenger side valve cover). If so, I don't really follow why you'd still pull from the passenger valve cover. I'd think you'd want to just cap the valve cover and pull only from the valley cover. Otherwise your diagram makes sense to me.
