The Cometic GM L42/L61 Gen-1/2 ECOTEC .027in MLS Cylinder Head Gasket - 89mm Bore - C5804-027 is a precision-engineered head gasket with a 89mm bore and .027" 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.
