Also, if you have pre-1960 heads, be aware you'll need valve covers with the offset bolt holes. Early heads had about 1/2" wider spaced bolt holes on the bottom of the valve covers. The original draft tube eliminator kits had a cone-shaped piece that bolted on with the draft tube attaching bolt, with a 3/8" hose nipple for the PCV valve to attach to. I installed a BUNCH of them when California made everybody retrofit draft tubes to PCV in the 1970's.
