Cometic MLS Cylinder Head Gasket Bore Thickness

The Cometic MLS (multi-layer steel) cylinder head gasket is a performance head gasket built to seal the cylinder head to the engine block. It holds up under high cylinder pressure, boost, nitrous and elevated combustion temperatures. It is a common choice for engine builders and racers who want a durable, reusable-quality seal for performance and race engines.

Key Features:

• Multi-layer steel construction: Stainless steel layers are stacked to give strength and consistent clamping force.
• Embossed sealing design: Raised embossments around the cylinder bores, fluid passages and fastener areas concentrate sealing pressure where it is needed.
• Coated surfaces: A specialized coating helps the gasket conform to the mating surfaces and resist corrosion and fluid seepage.
• Resists blowout: The rigid design resists the movement and deformation that can cause leaks in high-output engines.
• Selectable bore and thickness options: Multiple bore and thickness choices let builders set compression ratio and piston-to-head clearance for their application.

Cometic is known for precision-manufactured gaskets and seals for performance and racing use. Choose the bore and thickness that match your build, and follow proper surface preparation and torque procedures for best sealing results.
