Cometic C8961 Multi-Layer Steel (MLS) Head Gasket Pair .027 Inch

The Cometic C8961 is a Multi-Layer Steel (MLS) head gasket pair constructed from multiple layers of stainless steel for additional strength over traditional gaskets. These MLS gaskets feature an active combustion seal on multiple layers, with a compressed thickness of .027 inches.

Key Features:

• Comprised of three or five layers of stainless spring steel with embossed Viton coated stainless steel outer layers providing superior seal with excellent rebound characteristics and corrosion resistance
• Load-controlled embossments help conform load distribution across the sealing area
• Creates an exceptional seal by requiring less clamp load and resulting in less bore distortion
• Multi-Layer Steel head gaskets go on dry because they are coated with a .001 inch thick Viton rubber bonded to the outer stainless steel layers
• No sealants or re-torque required when properly installed on prepared surfaces
• Sold as a pair for complete cylinder head installation

Installation Requirements:

• MLS head gaskets require smooth, flat and true head and deck surfaces to seal
• A surface finish of 50 RA (roughness average) or finer is recommended for proper gasket seal
• Always refer to the manufacturer of the fastener to determine accurate torque values

Proprietary high temperature coatings along with embossments provide a micro seal for fluids against the head and block surface. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks.
