Cometic Gaskets 245-C5755-080 Features:
Buick Big Block V8 .080" MLS Cylinder Head Gasket, 4.400" Bore
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.

- 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
