According to the 1962 service manual California cars had a PCV valve and a tube from the valve cover to the air cleaner. It was NOT used on cars in other states, BUT was a dealer (or 0wner) installed option and came in a package. The intake was drilled and tapped for the 2 vacuum fittings. My 1962 Bonneville has this system and was a CA car. The valve cover hose went to a cap that looks the same as the one on the driver's side of your engine but was on the passengers valve cover.
