SKU: SKU: CGSC5987-027
The Cometic AMC 4.0L Inline 6 .027in MLS Cylinder Head Gasket - 3.950in Bore - C5987-027 is a precision-engineered head gasket with a 3.950" 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.
