Elevate Your Honda K-Series Performance with the Cometic 87mm Head Gasket

For those dedicated to pushing the limits of their Honda K-Series engines, the Cometic 87mm Head Gasket is engineered to deliver unparalleled performance.

Why Choose Cometic MLS Gaskets?

Cometic MLS Gaskets are crafted from multiple layers of stainless steel, offering exceptional strength, remarkable rebound capabilities, and resilience against corrosion. This ensures your engine is geared for maximum durability and reliability under extreme conditions.

Advanced Heat Resistance with Viton Coating

Each gasket’s outer layers are embossed and meticulously coated with Viton—a fluoropolymer elastomer based material capable of withstanding temperatures up to 250°C / 482°F. It's specifically designed to excel in harsh sealing environments, handling rigorous load conditions with ease for unmatched performance.

Customized Adaptability

The central layer, an uncoated stainless steel shim, can be varied in thickness to perfectly customize the gasket to suit your specific engine requirements, enhancing both fit and function.

Key Benefits
  • Ultimate Sealing Performance: Delivering top-notch sealing capability for today’s high-output engines without any additional sealants.
  • Perfect for Diverse Engine Builds: Ideal for setups involving aluminum heads to aluminum or cast iron blocks, adeptly handling the shearing forces between different materials.
  • Maintenance-Free Reliability: Thanks to its embossed MLS design, there’s no need to re-torque, ensuring an even clamp load which significantly reduces bore distortion.
