The '67 and '68 Zs used a smog tube and check valve for K19 equipped cars that stood further away from the valve cover than the more pedestrian 327 and 350 cars (different part number). This was to allow easier removal of the valve covers to adjust valve lash. I have forgotten if the '69 Zs had their own unique smog tubes for the middle position design that gave more clearance but I would guess somebody here knows for sure.
