Did your valve covers come with the baffle plates that mount below the hole you are going to drill for your breather/pcv?
Make sure you check for clearance with your rockers. They should clear stock vavletrain. I had to trim mine to clear the roller rocker adjuster.
Use the correct high temp lok tite on the screws that hold the baffle plates...you reeaally don't want one falling into the pan!
