Cometic MLS Cylinder Head Gasket GM Gen III/IV Bore

The Cometic MLS cylinder head gasket line for GM Gen III/IV V8 engines is a multi-layer steel (MLS) head gasket built for street performance, racing, and high-boost or nitrous-assisted builds. Cometic makes these gaskets for builders who need reliable cylinder sealing when stock composite gaskets are not enough.

Key Features:

• Multi-layer steel construction: Stacked stainless steel layers resist blowout, and the gasket keeps its sealing force under high cylinder pressure.
• Engineered for GM Gen III/IV engines: Available in a range of bore options for stock and aftermarket builds.
• Embossed sealing layers: Sealing beads work with the head and block surfaces to hold combustion, coolant, and oil passages.
• Coated surfaces: A coating helps the gasket seal against minor surface imperfections and resist corrosion.
• Durable and reusable-style design: MLS construction holds up through repeated heat cycles and high-load use.
• Made for performance builds: Suited to naturally aspirated, turbocharged, supercharged, and nitrous applications.
