About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring an outer coating of Viton rubber. This construction is designed to handle the demands of high-output engines, providing a strong seal without needing additional sealants. It's suitable for combinations of aluminum heads with aluminum blocks or aluminum heads with cast iron blocks, as it can manage the shearing forces that arise between different metals.

The gasket's layered stainless steel design offers increased strength and resilience, helping it rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton, a heat-resistant elastomer capable of withstanding temperatures up to 482°F (250°C) and performing well in harsh sealing environments. The center layer is uncoated stainless steel, and its thickness can be varied to meet different sealing requirements. When compressed, this gasket has an operating thickness of 0.098 inches.
