It's time to give your Big-Block Chevy a long overdue engine makeover. The new Slant-Edge look for big-block is the perfect way to customize your engine so it turns heads when you pop the hood at your local car show! With 13 different finish and Bowtie emblem combinations there's something for everyone, and the best part is that most these valve covers can be complemented with a matching Slant-Edge air cleaner, and breather caps to finish off the look in a perfectly coordinated way. There are three emblems to choose from: raised with a CNC machined finish, recessed and hand painted, blackfield recessed and raised, and lastly a new redfield recessed and raised. These premium die-cast aluminum valve covers have been optimized for maximum internal clearance, and feature innovative die-casting on the intake side so you don't have to struggle with bolts in tight places. Each pair of valve cover includes baffles, rubber grommets, and 6 special length mounting bolts for use on the intake side. Patent Pending.
