COMP Cams Billet Valve Covers for GM LS Race Applications are a sleek, high-quality billet aluminum valve cover designed to clear all types of valve train systems for LS engines, including shaft mount rockers. These valve covers feature an LS market first: internal valve spring oiling. While not required to be used, the spring oilers can significantly extend valve spring life in endurance applications. Also included are OE-style gaskets for superior sealing, as well as premium hardware and fasteners. Aimed at high end performance and racing applications, these valve covers have no coil mounting holes on the face, and the oil fill port has been removed to give a clean appearance while featuring internal baffling for an optional 3/8” breather or vent line. Black anodized for a sleek appearance, these valve covers are designed to fit all GM LS center bolt cylinder heads and are intended for applications that do not require an oil fill port in the valve cover, such as dry sump equipped race engines.
