The Cometic Gasket 487770 is a high-performance multi-layer steel (MLS) head gasket designed for demanding engine applications. Constructed with multiple embossed layers of stainless steel, the gasket features outer layers coated with Viton rubber, which provides excellent heat resistance up to 482°F (250°C) and durability in harsh sealing environments. This design ensures maximum sealing efficiency for high-output engines, eliminating the need for sealants and making installation straightforward. The gasket is suitable for use with aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, thanks to its ability to withstand shearing forces created by different materials. Its compressed operating thickness is approximately 0.036 inches, providing an optimal seal without excessive compression load. The center or shim layer is uncoated stainless steel, which allows for customization to achieve various thickness requirements, accommodating different engine setups. The embossed outer layers coated with Viton also contribute to enhanced rebound and corrosion resistance, ensuring long-term reliability under extreme conditions. This gasket is specifically designed for the Ford 5.8L Trinity Modular V8 engine, with a bore size of 95mm, and is suitable for engines in the 2013-2014 Ford Mustang as well as other compatible models. Its robust construction improves clamp load around the cylinder, reducing bore distortion and maintaining consistent compression for optimal engine performance. Whether rebuilding or upgrading, the Cometic MLX head gasket offers a reliable sealing solution for high-performance applications, delivering durability, excellent sealing, and compatibility across a range of engine configurations.
