- Cometic Big Block Chevy Marine Cylinder Head Gaskets
Cometic Multilayer Steel (MLS) Gaskets are designed to provide the best possible seal, even on engines used in marine applications. 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, and the gaskets have excellent rebound characteristics. MLS Cylinder Head Gaskets reduce bore distortion but can still endure extreme cylinder pressures. Sold individually.

Features:
- Made from stainless spring steel
- Exceptional resistance to corrosive substances
- 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)
