Help with adding breather to cast GM perf parts valve covers
I have a set of Cast GM performance parts valve covers for my BBC. The dreaded time has come to drill a hole for a breather. Anyone have any recommendations for a breather? As of now I was planning on drilling a hole and using a grommet that has the baffle molded into the rubber with a push in breather. I'm open to suggestions especially from anyone that has done this before. Thanks in advance
