Cometic NONSVO MLS Head Gasket for Select 1962-2000 Ford/Mercury 289/302/351 (4.03in Bore, .040in Thick)

This Cometic Multi-Layer Steel (MLS) Head Gasket is designed for high-output Ford 289, 302, and 351 small block V8 engines, providing a superior seal without the need for additional sealants. Featuring a 4.030-inch bore and a .040-inch compressed operating thickness, this gasket (MPN: C5511-040) is specifically engineered to handle the shearing forces found in high-performance applications, including mixed-metal configurations such as aluminum heads on cast iron blocks.

Constructed from multiple layers of embossed stainless steel, the outer layers are coated on both sides with Viton—a fluoroelastomer rubber based material that is heat resistant up to 250°C (482°F). This specialized coating ensures a reliable seal across various surface finishes and load conditions, while the stainless steel center shim allows for precise thickness requirements and provides the rebound needed to resist corrosion and maintain combustion pressure.
