If you have blow-by and how much will be more of a factor of your engine condition than the design of the PCV system. If your draft tube currently resembles a steam locomotive when you're going down the road, this swap isn't going to help that much at all. Adding the valve in the place of an open tube won't fix bad piston rings. Basically, what Ross has done is update his crankcase ventilation system to 1965 standards. It's a lot cleaner and more environmentally friendly than the stock system.

)I just want to take care of what little blow-by there is.
We have a 1967 Kaiser-Jeep M35A2 with a Continental Multi-Fuel engine. They have a vent below the turbo affectionately referred to as the "slobber tube". My flathead won't be anything like that.
