Cometic C10321-036 MLS Head Gasket Set 4.375" Bore .036" Thick Pair

The Cometic C10321-036 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket set designed for demanding V-twin applications. This pair of gaskets features a 4.375-inch bore diameter with a compressed thickness of .036 inches, providing precise combustion sealing for big bore engine builds.

Multi-Layer Steel Construction:

• Multiple embossed layers of stainless steel for superior strength and rebound characteristics
• Outer layers coated with proprietary high-temperature Viton-based material
• Active combustion seal on multiple layers for maximum sealing pressure
• Uncoated stainless steel center shim layer for dimensional stability

Advanced Sealing Technology:

• Load Control Embossments (LCE) promote even torque distribution across sealing surface
• Proprietary coatings provide micro-seal against cylinder head and block surfaces
• Reduces bore distortion for improved piston ring seal and increased power
• Requires less clamp load than traditional gaskets while maintaining superior seal

Key Specifications:

• Material: Multi-Layer Steel (MLS)
• Bore Size: 4.375 inches
• Compressed Thickness: .036 inches
• Quantity: Pair (2 gaskets)
• Construction: 3-layer design

Cometic MLS gaskets are engineered to withstand the extreme temperatures, pressures, and clamp loads of high-performance engines. The multi-layer construction allows the gasket to conform to imperfections in sealing surfaces while maintaining consistent sealing pressure around the combustion chamber. Ideal for naturally aspirated, turbocharged, supercharged, and nitrous oxide applications where reliable head sealing is critical.
