I'll do what you did. The DC valve covers are cool. Alter the baffles, drill holes and use the cork gaskets. The rubber gaskets leak. I think I'll have to use a PCV valve on one side and a breather on the other..just to be safe.
Check out his thread for pictures of my Direct Connection valve covers with breather and PCV. Notice how I turned the grommet upside down for the PCV (it works).
