Cometic Gasket BUICK LC2/LC4/LC6/LC8/LC9/LD5 V6 .040in MLS CYLINDER HEAD GASKET 3.860 in bore - c15577-040

The Cometic BUICK LC2/LC4/LC6/LC8/LC9/LD5 V6 .040in MLS CYLINDER HEAD GASKET 3.860 in bore - c15577-040 is a precision-engineered head gasket with a 3.860" bore and .040" 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.
