Cometic C8414 Multi-Layer Steel Head Gasket - 030 Inch

The Cometic C8414 is a high-performance Multi-Layer Steel (MLS) head gasket featuring a .030 inch compressed thickness, ideal for high-compression engine builds requiring precise sealing under extreme conditions.

Advanced Multi-Layer Steel Construction:

• Three-layer design with stainless steel center core sandwiched between two embossed spring steel outer layers
• Outer layers coated with high-temperature Viton rubber for superior sealing performance
• Embossed design with Load Control Embossments (LCE) distributes torque load evenly across sealing surface
• Non-intrusive rivets secure layers together while maintaining gasket integrity

Performance Benefits:

• Reduces bore distortion and improves piston ring seal for increased power output
• Withstands extreme cylinder pressures and shearing forces between dissimilar metals
• Excellent rebound characteristics and corrosion resistance from stainless steel construction
• Requires less clamping force than conventional gaskets while providing superior seal
• Suitable for both aluminum-to-aluminum and aluminum-to-cast iron applications

Installation Notes:

• Install dry—no additional sealant required due to factory Viton coating
• Requires smooth, flat machined surfaces with proper surface finish for optimal sealing
• Verify piston-to-head clearance (.030"-.032" recommended) before installation
• Consult fastener manufacturer for proper torque specifications

Cometic gaskets are engineered to meet the demanding requirements of high-performance, racing, and extreme-duty applications across powersports, automotive, and marine markets.
