Cometic C10321-030 MLS Head Gasket Set 4.375" Bore .030" Thick

The Cometic C10321-030 is a high-performance Multi-Layer Steel (MLS) head gasket set designed for demanding engine applications. This pair of gaskets features a 4.375-inch bore diameter and .030-inch compressed thickness, engineered to provide superior sealing under extreme cylinder pressures and temperatures.

Key Features:

• Multi-Layer Steel (MLS) construction for maximum durability and heat resistance
• 4.375-inch bore diameter for precise cylinder sealing
• .030-inch compressed thickness for optimal compression ratio control
• Pair of gaskets included for V-twin or multi-cylinder applications
• Designed for coolant passage heads with integrated cooling channels
• Superior torque retention and reusability compared to composite gaskets
• Embossed stainless steel layers with elastomeric coating for improved sealing

Cometic MLS head gaskets are a popular choice for high-performance and racing applications where reliability is critical. The multi-layer design allows for controlled compression and expansion during heat cycles, while maintaining consistent clamping force. These gaskets are ideal for boosted applications, high-compression builds, and engines subjected to extreme thermal stress.
