The Cometic 2004+ Ford 5.4L 3 Valve LHS 94MM .030 inch MLS Head Gasket - C5971-030 is a precision-engineered head gasket with a 94mm bore and .030" compressed thickness for the Left-Hand Side (LHS).

The Cometic Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers that conform to surface irregularities and maintain a positive seal. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.
