Ok I bought the black wrinkle Mopar Performance valve covers this weekend. I got the grommets specified by Year One yesterday for the PCV and breather. Now do I need to take these to a machine shop to open up the breather and pcv grommet holes or is it something I can take to any kind of repair shop to do? These are a lot taller than the original ones, I hope they clear on the passenger side with the original fuel line right at the corner. I got the Mr. Gasket Ultra Seal valve cover gaskets that say they are reuseable, but I doubt it once I put it on this motor. I wanted the Mopar Performance red ones but no one had them. The Moroso blue Perma-Align gaksets only fit Moroso valve covers so the guy wouldn't sell them to me. The Mr. Gasket was the best one I could find. I opted for all studs and nuts over the recommended screws from Mopar Performance. I hate putting these on there but if it will seal then it's ok. They sure don't like they'll warp as easily as the original steel ones.
