Cometic C4140-070 MLS Cylinder Head Gasket Bore Thick - 84mm 070

The Cometic C4140-070 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed for high-performance Ford Kent engines and their derivatives. This .070" (1.78mm) thick gasket features an 84mm bore diameter and is specifically engineered for Ford Pre-Crossflow OHV Kent, Crossflow OHV Kent, Cosworth BD Series, and Lotus Twin Cam applications.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
• .070" compressed thickness allows for precise compression ratio tuning
• 84mm bore diameter optimized for classic Ford Kent engine family
• Compatible with Ford Pre-Crossflow and Crossflow OHV Kent engines
• Engineered for Cosworth BD Series and Lotus Twin Cam performance applications
• Embossed stainless steel layers with elastomeric coating ensure excellent conformability
• Resists blowout and coolant seepage better than traditional composite gaskets

Cometic MLS gaskets are the preferred choice for high-performance and racing applications where reliability and consistent sealing are critical. The multiple layers of stainless steel provide the strength needed to withstand high cylinder pressures while the proprietary coating ensures optimal sealing on both smooth and slightly imperfect deck surfaces.
