Cometic C10309-030 MLS Head Gasket Set 4.295" Bore .030" Thick

The Cometic C10309-030 is a premium Multi-Layer Steel (MLS) head gasket set designed for high-performance applications requiring exceptional sealing and durability. This gasket features a 4.295-inch bore diameter with a compressed thickness of .030 inches, providing precise compression control and reliable sealing.

Key Features:

• Multi-Layer Steel (MLS) construction for superior strength and conformability
• 4.295-inch bore diameter accommodates larger cylinder bores
• .030-inch compressed thickness for custom compression ratio tuning
• Integrated oil and coolant sealing rings for leak-free performance
• Sold as a pair (PR) for multi-cylinder applications
• Heavy-duty MIL specification construction withstands extreme cylinder pressures
• Eliminates gasket failure and head lifting under high boost or compression

Cometic MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that micro-seal surface imperfections while maintaining torque retention. The advanced design allows the gasket to rebound and compensate for minor surface irregularities and thermal expansion, making it ideal for turbocharged, supercharged, and high-compression naturally aspirated engines.
