The Cometic GM/Mercury Marine 525/625 502 Gen-VI Big Block V8 .051in MLS Cyl Head Gasket-4.470in Bore - C5760-051 is a precision-engineered head gasket with a 4.470" bore and .051" compressed thickness.

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.
