Cometic Gaskets 245-C5457-030 Features:
Chrysler LA V8 .030" MLS Cylinder Head Gasket, 4.125" Bore
Cometic Multilayer Steel (MLS) Gaskets are designed to offer the best seal for naturally-aspirated, boosted, or nitrous-fed engines. Head gaskets are made of 3-5 layers of spring stainless steel, providing a stronger base material than standard cylinder head gaskets. Viton-coated stainless steel outer layers create a superior seal not available with other steel or copper gaskets. The gaskets have excellent rebound characteristics and resist corrosive substances. MLS head gaskets reduce bore distortion but can still endure extreme cylinder pressures. Sold individually.

- Always refer to the fastener manufacturer to determine accurate torque values
