The Cometic C10346-052 is a pair of high-performance Multi-Layer Steel (MLS) head gaskets designed for engines with a 4.250-inch bore diameter. These gaskets feature Cometic's proven MLX (Multi-Layer Stopper) construction with a compressed thickness of .052 inches, providing exceptional sealing performance under extreme cylinder pressures.

Key Features:

• Multi-Layer Steel (MLX) construction for maximum durability and superior sealing
• 4.250-inch bore diameter with 4.270-inch inner diameter for precise fitment
• .052-inch compressed thickness for optimal compression ratio control
• Integrated oil and coolant sealing passages engineered for leak-free performance
• Sold as a pair for dual-engine applications or replacement inventory
• Viton rubber gasket material on outer layers bonds to steel core for superior blowout resistance
• Ideal for high-performance, racing, and forced induction applications

Cometic MLS head gaskets are the choice of professional engine builders and racers worldwide. The multi-layer design allows the gasket to adapt to minor surface imperfections while maintaining consistent clamping pressure across the entire sealing surface. These gaskets accommodate thermal expansion and contraction better than traditional composite gaskets, making them perfect for turbocharged, supercharged, and high-compression naturally aspirated engines.
