Cometic C4258-060 Head Gasket

Cometic Multilayer Steel (MLS) Gaskets are designed to provide the best possible seal for naturally aspirated, boosted, or nitrous-fed engines. This head gasket is made from five layers of spring stainless steel, offering a stronger base material than standard cylinder head gaskets. Viton-coated outer layers create a superior seal not available with other steel or copper gaskets.

Cometic C4258-060 Head Gasket Features:

• Spring stainless steel
• Reduced bore distortion
• Excellent rebound characteristics and corrosion resistance
• Viton rubber coating (.001 in. thick) is bonded to the outer layer of gaskets
• Designed to withstand extreme cylinder pressures without machining for installation of locking wire

Cometic C4258-060 Notes:

• Not designed for use on engines with O-rings or receiver grooves
• Always refer to the fastener manufacturer to determine accurate torque values
• A surface finish of 50 RA (roughness average) or finer is recommended for proper gasket seal
• Cometic Cylinder Head Gaskets go on dry because they're coated with a sealant (adding another sealer can hinder gasket performance)
