Dennis,
Whether or not the Billet Specialties PCV or any PCV valve will operate in your motor depends upon how much intake manifold vacuum you have at idle. You need enough vacuum to "suck" the valve closed. It easy enough to test, just start the motor, let it idle, pull the PCV valve out of the valve cover, turn it over and observe the valve plug. It should be closed tightly so that it can't suck air into the motor at idle

George,
I’ve reread this section a number of times but I still might be misunderstanding what you are describing.
Here is how I have it set up on my Pantera. At idle and deceleration, e.g. high vacuum, the valve is open with some regulated flow. Meaning if you look at the end of the valve you will see an opening and air can flow through it. When the engine is off the valve will be closed and during a back fire. So at a normal idle, the valve will be open and a regulated air flow is present. The air flow and regulation of the valve orifice changes depending on vacuum or air flow available.
In my case, filtered air from inside the air cleaner is flowing through the hose to the back right valve cover cap, through the cap, through the engine and up into the left valve cover, through the open PCV valve, into the intake manifold and into the combustion of the engine. Here is a link that has some helpful diagrams http://www.aa1car.com/library/pcv.htm
It is possible that you are describing the same thing and I’m just misreading it.
