Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under high-compression and high-performance conditions
• .066-inch compressed gasket thickness for precise compression ratio tuning
• 4.300-inch bore diameter accommodates stroker and big-bore FE builds
• Premium gasket material resists blowout and maintains seal integrity under extreme cylinder pressures
• Engineered for Ford FE V8 engines including 352, 360, 390, 406, 410, 427, and 428 cubic inch variants

Important Compatibility Note: This gasket does NOT fit the 427 SOHC (Single Overhead Cam) "Cammer" engine due to different head bolt patterns and combustion chamber geometry.

Cometic MLS gaskets feature multiple layers of stainless steel with unique coatings that allow the gasket to adapt to sealing surface imperfections while maintaining excellent recovery properties. This makes them ideal for high-performance street engines, racing applications, and boosted combinations where reliable head sealing is critical.
