The Cometic 66-84 Harley-Davidson Shovelhead Std Bore .066in MLS Head Gasket - 2 Pack - C9984-066 is a precision-engineered head gasket with a .066 bore and .066" compressed thickness sold in a 2-pack.

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.
