I was wondering what I should put in those holes. I was looking around summit, but I'm still not sure. I have the ford racing chrome valve covers. I'm pretty sure since I have fuel injection and all the emissions crap, I shouldn't go with just an open breather. I'm also fairly certain I should retain that tube that goes from the valve cover to the intake pipe. So that narrows down my choices, but my question is should I get a valve cover breather "with PCV" or the ones without the PCV? Maybe if somebody could just give me a link to the correct part off of Summit, that would be great too. Thanks for the help once again.
