darn, you really know your crankcase evacs! haha you described my setup perfectly piece for piece. I would just hook up the same exact system but i have a couple of variables that don't allow that.
1) new air cleaner that doesnt connect to the valve cover
solution: K&N breather on valve cover?
2) new offenhouser dual carb intake manifold, which doesnt provide a large enough pipe thread for the brass piece
solution: use smaller hose fitting that is provided on the intake and connect that to a new AC spark plug and then into the side of the valve cover.
will this work?
