Cometic GM Gen-V/VI Big Block MLS Cylinder Head Gasket Bore

The Cometic Gen-V/VI Big Block MLS cylinder head gasket is a multi-layer steel (MLS) head gasket for GM Gen-V and Gen-VI big block V8 engines. It is made for high-performance street, strip and racing builds. It seals the cylinder head to the block and holds up under high cylinder pressure, boost and nitrous.

Key Features:

• Multi-layer steel construction: Layers of embossed stainless steel give strong, consistent sealing and resist heat and combustion pressure.
• Stainless steel combustion seal: The bore sealing area is designed to resist blow-by and gasket failure in demanding applications.
• Coating: Cometic applies a coating to the gasket surfaces to help it seal and to help keep it from sticking to the head and block.
• Reusable and durable: MLS gaskets resist compression set and hold their seal through repeated heat cycles.
• Multiple options: Bore and thickness options are offered as separate part numbers, so you can match the gasket to your engine's bore and desired compression.

Cometic is known for precision-manufactured gaskets used in professional racing and performance engine building. Proper deck surface finish and correct head bolt or stud torque are recommended for best sealing results. Choose the correct variant for your cylinder bore and build specifications.
