Cometic GM Small Block MLS Head Gasket Bore

The Cometic GM Small Block MLS head gasket line is a multi-layer steel (MLS) cylinder head gasket for small block Chevrolet and GM V8 engines. It is made for street performance, racing, and high-boost or nitrous builds. Each gasket seals the cylinder head to the engine block. MLS construction also goes by the names multi-layer steel head gasket and MLS cylinder head gasket.

Key Features:

• Multi-layer steel construction: Stainless steel layers are stacked to seal well under high cylinder pressure and heat.
• Coated sealing surfaces: A coating on the outer layers helps the gasket conform to the head and block surfaces and seal reliably.
• Embossed sealing design: Embossed layers create a high-pressure seal around the combustion chamber, coolant passages, and oil passages.
• Reusable: MLS gaskets resist compression set better than composite gaskets and are well suited to engines that are assembled and torqued more than once.
• Multiple bore and thickness options: The line is offered in a range of bore diameters and compressed thicknesses so builders can set compression ratio and piston-to-head clearance. Choose the option that matches your build.

Cometic is a well-known maker of performance gaskets for racing and high-performance engines. For best results, use clean, flat head and block surfaces, and follow the recommended surface finish and torque procedure for your fasteners.
