Cometic Gaskets 245-C5879-040 Features:

Cometic Multilayer Steel (MLS) Gaskets are designed to provide the best possible seal for naturally-aspirated, boosted, or nitrous-fed engines. These head gaskets are made from 3 to 5 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 MLS Cylinder Head Gaskets reduce bore distortion but can still endure extreme cylinder pressures. Sold individually.

Features:

Made from stainless spring steel
Excellent rebound characteristics and corrosion resistance
Viton rubber coating (.001'' thick) is bonded to outer layer of gaskets
Designed to withstand serious cylinder pressures without machining for installation of locking wire

Installation 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)
