Not Ranked
I think the standard without PVC is at least two breather locations to have some degree of in/out cross ventilation. With a rear breather, my barely worth 2 cents worth is that you probably need a PVC line pulling off of a valve cover for best ventilation. If your vacuum port is also at the rear of the intake it will short circuit with the rear-mounted breather. May still work - just not as effectively (at least in my humble, barely-informed opinion).
