Description

The Cometic C5633-120 is an MLS (Multi-Layer Steel) cylinder head gasket designed for Chrysler LA V8 engines. It features a compressed operating thickness of 0.120 inches and a 4.040-inch bore size. The gasket's outer layers are coated with Viton rubber, which is heat resistant up to 250°C (482°F).

Constructed from multiple embossed layers of stainless steel, this gasket provides maximum sealing performance for high-output engines and does not require sealants. It is suitable for applications with aluminum heads on aluminum blocks or aluminum heads on cast iron blocks, capable of withstanding the shearing forces between dissimilar materials.
