Cometic MLS Cylinder Head Gasket Bore Chevy Small Block

The Cometic MLS cylinder head gasket for Chevy small block engines is a multi-layer steel (MLS) head gasket. It is built for street performance, racing, and high-output engine builds. Also called a multi-layer steel head gasket, MLS head gasket, or SBC head gasket, it seals the cylinder head to the block and holds up under high cylinder pressure, heat, and boost.

Key Features:

• Multi-layer steel construction: Stacked stainless steel layers resist blow-by and hold up to repeated heat cycling.
• Coated surfaces: Cometic applies a coating to the gasket surfaces to help seal and to resist corrosion.
• Stopper-style sealing: Embossed sealing rings and stopper layers concentrate clamping load around the bore and fluid passages.
• Multiple configurations: The product line comes in several bore sizes and compressed thicknesses, so builders can match the gasket to their engine's bore, deck height, and compression targets.
• Precision manufacturing: Cometic is a well-known maker of performance gaskets and manufactures them in the USA.

These gaskets are a durable replacement for composite head gaskets in engines that see higher cylinder pressure, nitrous, or forced induction. Choose the bore size and thickness that match your build. Follow the gasket and head fastener manufacturers' recommendations for surface prep and torque procedure.
