The Cometic GM SB2.2 Small Block V8 .066in MLS Cylinder Head Gasket - 4.125in Bore - With Steam Holes - C5321-066 is a precision-engineered head gasket with a 4.125" bore and .066" 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.

  • Bore Size: 4.125"
