I'm leaning to the cast covers for looks, anyway - but not soon, if I don't have to. I think the rear PCV and a closed, vented breather on the filler might be the best setup.
Speaking purely in terms of efficiency and operation, does PCV that pulls only through the lifter valley do as good a job as a full cross-venting from valve cover to valve cover? I'm finding conflicting information. Someone above said the valve cover venting is purely automaker convenience and I've heard that elsewhere as well.
It's also unclear whether PCV requires carb vacuum or intake vacuum. Most OEM setups go to the base of the carb, which has a slightly different vacuum profile than the intake. However, my intake has a nice plugged port right below the carb... I could make the PCV valve plumbing damn near invisible.
