Cometic MLS Head Gasket Bore Thickness

The Cometic MLS head gasket (multi-layer steel cylinder head gasket) is built for engines that need reliable sealing under higher cylinder pressures, boost, nitrous, and high-RPM use. Cometic offers it in a range of bore diameters and compressed thicknesses. This lets engine builders match the gasket to their build, setting piston-to-head clearance and compression ratio.

Key Features:

• Multi-layer steel construction: Stacked stainless steel layers give strong, durable sealing and resist blowout in demanding applications.
• Embossed sealing surfaces: Embossments around the combustion openings and fluid passages concentrate clamping load where it is needed to seal combustion pressure, coolant, and oil.
• Protective coating: A coating on the outer layers helps the gasket seal against the block and head surfaces and resists corrosion.
• Selectable bore and thickness: Choose the bore size and compressed thickness that suit your piston, deck height, and compression goals.
• Precision manufacturing: Cometic is known for accurately made gaskets for performance and racing engines.

Cometic MLS head gaskets are a popular choice for street performance, turbocharged, supercharged, and racing builds. They are also used for engine rebuilds where a durable, reusable-quality sealing solution is wanted. For best results, use clean, flat sealing surfaces and follow the engine builder's recommended fasteners, torque sequence, and surface finish specifications.
