What is the compressed thickness of this head gasket?

When properly compressed during installation, this Cometic head gasket has an operating thickness of .036 inches. This is achieved through its multi-layer steel design with a specific shim layer.

What is Viton and why is it used on this gasket?

Viton is a type of synthetic rubber that is highly resistant to heat, withstanding temperatures up to 482°F (250°C). It's used as a coating on the outer layers of this gasket to ensure a reliable seal in demanding engine environments.

Do I need to use any sealant with this head gasket?

No, Cometic Multi-Layer Steel (MLS) head gaskets are designed to provide maximum sealing performance on their own and do not require additional sealants for installation.

About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer coating of Viton rubber on both sides. It's designed for an 87.5mm bore and has a compressed operating thickness of .036 inches, making it a solid choice for your H23A1 engine build. MLS gaskets are known for their ability to handle the demands of high-output engines and provide maximum sealing performance without needing additional sealants.

The stainless steel construction offers increased strength and resistance to corrosion, while the Viton coating is heat-resistant up to 482°F (250°C), ready to handle harsh sealing environments and varying surface finishes. This design is effective whether you're pairing aluminum heads with an aluminum block or aluminum heads with a cast iron block, as it can manage the shearing forces that can occur between different metals. The center shim layer is uncoated stainless steel, allowing for adjustments in thickness to meet specific engine requirements.
