Adjustable PCV valve

The M/P covers are baffled. I have 14 inches at hot idle and like 20 cruising. It's pretty amazing considering it's a 520/540 282S solid cam with dual 450s. I hooked up a generic parts store one because those numbers are pretty "stock"and yes I need to jet up a little according to my O2 sensor. Again just wondering what people have been doing with there pcv systems and input on the adjustable one.
