Shark Gray is the latest Chevrolet Performance finish...sleek and subtle to give your engine bay a really well coordinated look! For Chevrolet big-block engines, V8, 1965-96. These tall stamped steel valve covers are electrostatically painted and baked with a durable high-tech, gray epoxy, and finished with the famous Chevrolet and Bowtie emblems. These CHEVROLET Bowtie valve covers are made of heavy-gauge steel, 20% thicker than typical aftermarket valve covers, greatly reducing the likelihood of leakage around the valve cover flange area caused by fasteners being over-torqued. Stamped valve covers are offered in either tall or production height (short). Oil restricting baffles are offered in many valve covers for those who w ish to maintain the PCV hookup. All valve covers are sold in pairs, equipped with air breather and PCV grommets, unless specified otherwise.
