360 oil leak at back of intake manifold

You have a very valid point..... I have recently purchased a dual circuit PCV valve from ME Wagner. Trying to get through startup & yes this has been discussed with ME Wagner and the valve is currently set as ME Wagner suggests for startup. What little testing I was able to do on my Holly HP 750 PCV valve port has shown I have 10 inches vacuum at idle and 19 inches at cruise speed (using 2500-3000 RPM as target) I will be back on it this weekend so i should have some updates as the weekend closes out.
