On the front of the upper intake manifold, there is a vacuum return line fitting. That your PCV return tube connected to. Plug that or you'll have a major vacuum leak. I just use a large black vacuum cap. I'd put a breather on the passenger side then, and plug the drivers. It'll be like stock then, except you have a vented pressure release instead of a draw-through. Mine is set up this way, with the stock valvecovers, and I have no problems whatsoever.
