Cometic C10250-030 MLS Head Gasket Bore Thick - 3.937 030

The Cometic C10250-030 is a Multi-Layer Steel (MLS) head gasket designed for high-performance engine applications. This precision-engineered gasket features a 3.937-inch bore diameter and .030-inch compressed thickness, making it ideal for custom engine builds requiring specific compression ratios.

Key Features:

• Multi-Layer Steel construction for superior sealing and durability
• 3.937-inch (100mm) bore diameter
• .030-inch compressed thickness for fine-tuning compression
• Designed for approximately 107 cubic inch displacement applications
• Exceeds OEM specifications for strength and reliability
• Resists compression set and maintains consistent clamping force
• Compatible with various surface finishes and head materials

Cometic MLS head gaskets are constructed with multiple layers of stainless steel, providing exceptional conformability to sealing surfaces while maintaining the strength needed for high-compression and boosted applications. The embossed layers create a gas-tight seal that accommodates thermal expansion and cylinder pressure fluctuations better than traditional composite gaskets.
