Constructed from multi-layer steel, this head gasket offers durability and reliable sealing. It features a 3.910-inch bore and a compressed thickness of 0.051 inches, designed to provide a precise fit for compatible LS engine applications. These gaskets are sold as a pair, ensuring both cylinder heads are covered for a complete installation. This head gasket set is suitable for LS1 and LS6 engines.
