The Cometic C5691-095 is a Multi-Layer Steel (MLS) cylinder head gasket designed for Buick Stage I/Stage II V6 engines. It features multiple embossed layers of stainless steel with an outer Viton rubber coating for enhanced sealing performance.

This gasket has a compressed operating thickness of 0.098 inches and offers maximum sealing for high-output engines. It is ideal for use with both aluminum and cast iron blocks, capable of withstanding shearing forces and resisting corrosion. The Viton coating provides heat resistance up to 250 C/482 F, meeting demands of harsh sealing environments.
