I am installing an IAG Competition AOS and an Oil Control valve from Killer Bee. Not sure how to plumb it. Oil control valve is suppose to connect to both heads and a vacuum source. The AOS wants 2 head ports and vacuum as well I suspect. Any help would be appreciated. What is the difference in these 2 ports? Then of course I have the stock PCV up front that is where I think the IAG connects for vacuum.
