Glad the info is of some help Joe.
Just a note that if you are wanting this to be a true "closed" PCV system, use of the "breather" through the side port on valve cover kind of defeats that. I found a small write-up in a Hemmings article which I have clipped as an attachment below to maybe better describe how the "closed" system works.
Others may chime in with added input as may be helpful.
Would be interested to see what you end up with.
