Cometic Ford Boss 302 .027in MLS Cylinder Head Gasket - 4.080in Bore

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. When compressed, it measures .027 inches thick, providing a solid seal for high-output engines. These MLS gaskets are well-suited for applications joining aluminum heads to either aluminum or cast iron blocks, as they can handle the shearing forces that arise from dissimilar materials. The multiple stainless steel layers offer increased strength and the ability to rebound, while also resisting corrosion. The Viton coating on the outer layers is a heat-resistant material designed to perform in demanding sealing environments and under various load conditions. The center layer is uncoated stainless steel and can be varied to achieve different thickness requirements.

Because they are constructed from multiple layers of stainless steel, these gaskets offer improved strength and resilience. The outer layers are embossed and coated on both sides with Viton, a high-temperature resistant elastomer capable of handling up to 482 degrees Fahrenheit. This makes them ideal for engines that run hot or require a dependable seal under pressure. The center shim layer is made of stainless steel and is uncoated, allowing for adjustments in gasket thickness to meet specific engine build needs. These gaskets do not require additional sealants, simplifying installation.
