Opinion on PCV valve for flathead?

Yes the pan vent needs to be blocked. Not sure about the pcv hose going below the blower, these pcv chaps work with vacuum not boost.
I personally would not use a pcv on a supercharged engine. It creates a vacuum leak to the manifold and that vacuum is pulling oil vapour laden air into the engine. This lowers the octane and increases the chance of destination. Just a bad idea in my mind.
