I removed the factory breather nipples and had them machined to a -6 ORB thread. Heres a couple pictures and also the fitting to be used (I will use a black aluminum fitting rather than a silver steel one). The fitting is not tight in the valve cover in the picture but the O-ring does bottom and fits perfect. Any others from Alberta or anyone that want this done PM me and I will send you the machinists information. He built a special tool to do this for me.
