Cometic C5731-066 Ford MLS Cylinder Head Gasket Bore Thick - 460 4.600 066

The Cometic C5731-066 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Ford D/E 460 cubic inch Pro Stock applications. This high-performance gasket features a 4.600-inch bore diameter and .066-inch compressed thickness, making it ideal for serious racing engines that demand superior sealing under extreme cylinder pressures.

Key Features:

• Multi-Layer Steel (MLS) construction provides maximum sealing and durability
• 4.600-inch bore diameter accommodates oversized pistons in big-bore builds
• .066-inch (1.68mm) compressed thickness for precise compression ratio tuning
• Designed specifically for Ford 460 Pro Stock racing applications
• Superior torque retention and blowout resistance under high cylinder pressure
• Eliminates gasket failure common with composite gaskets in high-performance engines

Cometic MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that recover and seal better than traditional gaskets. The embossed sealing beads ensure proper compression loading around the combustion chamber, coolant passages, and oil return holes. This gasket is a critical component for engine builders looking to maximize reliability in Pro Stock, drag racing, and other extreme high-performance Ford 460 applications.
