Proflow's LS valley covers are the latest accessories offered for the GM LS engine. These valley covers are for people looking to dress up their engines, allowing for the elimination of Displacement-On-Demand (DOD), and instead featuring an ample composite gasket and sealing surface. This valley cover comes with a -06AN breather port to connect accessories such as oil catch cans. They are available in a black anodized or a polished billet aluminium finish to match Proflow's popular valve covers. Comes with bolts and gasket.
