Cometic Ford SB 4.155 inch Bore .080 inch MLS-5 Head Gasket (w/AFR Heads)

The Cometic Ford SB 4.155 inch Bore .080 inch MLS-5 Head Gasket is a high-performance sealing component designed for demanding engine applications. Constructed with multiple embossed layers of stainless steel, the outer layers are coated with Viton rubber to enhance heat resistance and sealing durability. With a compressed thickness of 0.080 inches, this gasket is engineered to provide maximum sealing performance without the need for sealants. It is suitable for use with AFR heads featuring a coolant eyebrow and is compatible with both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. The multi-layer steel design offers increased strength, rebound capability, and corrosion resistance, making it ideal for high-output engines and harsh environments.

Designed for use with Ford small block engines with a 4.155-inch bore, this MLS gasket serves as a direct replacement or upgrade for stock head gaskets. It is suitable for high-performance street, track, or racing applications where reliable sealing under extreme conditions is critical. The gasket’s construction allows it to withstand shearing forces created by different materials and surface finishes, ensuring long-lasting performance. Installation involves replacing the existing head gasket with this MLS component, which is compatible with engines that have AFR heads with coolant eyebrows. This gasket provides a secure, leak-free seal for high compression and boosted engines, supporting optimal engine performance and durability.
