Default Re: Opinion on PCV valve for flathead?

Update on the pcv install. I found a dual circuit pcv valve made by Wagner so you can adjust your idle and cruise vacuum requirements separately as well as how much vacuum you're pulling through the pcv. At idle, I'm at 2 inches and cruise about 7 inches. I ran the return back to the carb through a catch can set-up that has a 50 micron bronze filter to help clean up the air a bit and remove moisture or oil before it's reintroduced into the motor. I also installed a K&N breather cap and blocked of the oil pan vent. I just went for a test run and I din't notice any changes as far as air/fuel ratio's.
I did notice that when I'm stopped at a light there's no more smoke!! This is a plus and the main reason I installed this set-up. I know some of you will say it's too expensive and unnecessary, but with the supercharger and detonation being a potential problem, I wanted to be able to adjust the system accordingly. It's a small price to pay compared to a burnt up motor.
