Cometic C10284-020 MLS Head Gasket Bore Thickness - 4.250 020

The Cometic C10284-020 is a Multi-Layer Steel (MLS) head gasket designed for high-performance engine applications requiring precise sealing and durability. This gasket features a 4.250-inch bore diameter and .020-inch compressed thickness, making it ideal for engines with specific bore requirements and custom compression ratio tuning.

Key Features:

• Multi-Layer Steel (MLS) construction for superior strength and conformability
• 4.250-inch bore diameter for precise cylinder sealing
• .020-inch compressed thickness allows for compression ratio adjustment
• Sold as a pair for V-twin or multi-cylinder applications
• Advanced coating provides excellent sealing for both oil and coolant passages
• Designed to withstand extreme cylinder pressures and temperatures
• Eliminates gasket failure and coolant leaks in high-performance builds

Cometic gaskets are precision-manufactured using computerized CNC cutting technology to ensure exact fitment and reliable sealing. The MLS design features multiple layers of stainless steel with specialized coatings that allow the gasket to conform to imperfect sealing surfaces while maintaining exceptional blowout resistance. This gasket is ideal for racing applications, forced induction setups, and high-compression naturally aspirated engines where reliability under extreme conditions is critical.
