Cometic C4606-036 MLS Cylinder Head Gasket 87mm Bore .036 in

The Cometic C4606-036 cylinder head gasket (also called a head gasket or MLS head gasket) is a multi-layer steel design for high-output engines. It has an 87mm bore and a .036" compressed thickness. It seals the cylinder head to the block and is built for tuned, high-compression and boosted builds.

Key Features:

• Multi-layer steel (MLS) construction with embossed stainless steel layers
• Outer layers are coated on both sides with Viton, which resists heat up to 250°C / 482°F
• Uncoated stainless steel center shim layer sets the overall thickness
• Works with aluminum heads on aluminum or cast iron blocks
• Needs no additional sealants
• Resists corrosion and rebounds as the head and block expand and contract
• .036" compressed thickness lets you fine-tune compression ratio

Cometic MLS head gaskets need less clamp load, which reduces bore distortion and spreads load evenly across the sealing area. For best sealing, Cometic recommends a mating surface finish of 50 Ra or finer.
