Cometic C9314G MLS Multi-Layer Steel Cylinder Head Gasket

The Cometic C9314G is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket built for high-performance and racing applications where a reliable, leak-free combustion seal is critical. Cometic Gasket is a globally recognized leader in performance sealing technology, designing gaskets to meet and exceed the demands of modified and built engines.

MLS Construction:

• 3-layer stainless steel design — a solid stainless steel center shim layer sandwiched between two embossed outer layers for consistent clamping force and superior rebound
• Viton (FKM) fluoroelastomer coating on both sides of the outer layers — heat-resistant to 482°F (250°C) and resistant to oil, coolant, and combustion gases
• Load-controlled embossments distribute clamping force evenly across the sealing surface, reducing bore distortion and requiring less overall clamp load
• Compatible with aluminum head-to-cast iron block and aluminum head-to-aluminum block combinations
• Withstands the shearing forces generated by dissimilar metal head and block pairings

Installation Notes:

• Installs dry — no additional sealant required; each MLS gasket is pre-coated with a .001" Viton rubber layer bonded to the outer steel layers
• Head and deck surfaces must be smooth, flat, and true — a surface finish of 50 RA (roughness average) or finer is required for a proper seal
• No re-torque is necessary after installation
• Always refer to the fastener manufacturer for correct torque specifications

The Cometic C9314G MLS head gasket is a trusted choice for professional engine builders and motorsport enthusiasts who demand a dependable, high-performance combustion seal for street and track use.
