Cometic Ford 289/302/351 4.155 inch Bore .027 inch MLS Head Gasket (Non SVO)

Starting with a compressed operating thickness of 0.027 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious performance. It's constructed from multiple layers of stainless steel, with the outer layers featuring a heat-resistant Viton rubber coating. This design is ideal for sealing aluminum heads to either aluminum or cast iron blocks, effectively handling the shearing forces that can occur between different metals. The stainless steel layers provide increased strength and the ability to rebound, while also resisting corrosion. The Viton coating on the outer layers is designed to handle harsh sealing environments and varying surface finishes, meeting the demands of high-output engines without needing additional sealants.

This gasket is a solid option for a wide range of Ford Windsor V8 applications, including vehicles like the Ford Bronco, Ford E-Series vans, and even classic AC Shelby Cobras. The multi-layer steel construction offers improved sealing performance compared to traditional composite gaskets, making it well-suited for engines that push beyond stock power levels. The center shim layer can be varied to accommodate different thickness requirements, and in this case, it's set to a .027 inch compressed thickness for optimal performance in its intended applications.
