The Cometic GM LS1/LS2/LS3/LS6 Gen-III/IV Small Block V8 .051in MLS Cylinder Head Gasket 4.030in Bore - C15494-051 is a precision-engineered head gasket with a 4.030" 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.
