The Cometic Ford SB 4.080 inch Bore .066 inch MLS-5 Head Gasket (w/AFR Heads) - C5910-066 is a precision-engineered head gasket with a 4.080" bore and .080" compressed thickness.

The Cometic 5-Layer Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring 5-Layer Multi-Layer Steel (MLS) construction, this gasket uses five embossed steel layers delivering exceptional clamping load distribution for high-output applications. 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.
