What is the compressed thickness of this head gasket?

This Cometic Multi-Layer Steel (MLS) head gasket has a compressed operating thickness of 0.030 inches. This measurement is crucial for maintaining proper compression ratios after installation.

Does this head gasket require any sealant during installation?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance on their own and do not require any additional sealants. This simplifies the installation process.

What makes the Viton coating on the outer layers important?

The Viton rubber coating on the outer layers is a heat-resistant elastomer that can withstand temperatures up to 482°F (250°C). This makes the gasket suitable for demanding sealing environments and helps ensure a reliable seal under various operating conditions.

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 layer coated with Viton rubber. It's designed for a compressed operating thickness of 0.030 inches and is specifically for the left side of Ford 5.4L 3-valve engines with a 94mm bore, commonly found in vehicles like the Ford Expedition, F-150, and Mustang.

MLS gaskets are a strong choice for high-output engines because they offer maximum sealing performance without needing additional sealants. They handle the stresses between aluminum heads and either aluminum or cast iron blocks well. The multiple stainless steel layers give these gaskets increased strength and the ability to rebound, while also resisting corrosion. The Viton coating on the outer layers is heat resistant up to 482°F (250°C), making it suitable for harsh sealing environments and various surface finishes. The center layer is uncoated stainless steel, allowing for adjustments in thickness requirements.
