About Cometic Gasket

Cometic Gasket is the world leader in custom multi-layer steel head gaskets for performance and motorsport engines. From off-the-shelf MLS for popular platforms to bespoke gaskets for race-only builds, Cometic seals everything from Honda B-series to LSX.

High-Performance Sealing for 5.7L Hemi Engines

Ensure your engine build maintains maximum compression with the Cometic .027 inch MLS (Multi-Layer Steel) head gasket. Specifically designed for the 5.7L Hemi platform, this gasket provides a robust seal for high-output applications. The multi-layer stainless steel construction offers superior rebound and corrosion resistance compared to standard gaskets.

Technical Specifications

  • Bore Size: 3.950 inches
  • Compressed Thickness: .027 inches
  • Material: Multi-Layer Stainless Steel
  • Coating: Viton rubber (heat resistant to 482°F)
  • Application: Left Hand Side (LHS)

The outer layers are precision-embossed and coated with Viton, a high-temperature fluoroelastomer that conforms to surface finishes, ensuring a leak-free seal even under extreme cylinder pressures. This design is ideal for both aluminum and cast-iron block combinations, effectively managing the shearing forces generated by thermal expansion. Whether you are refreshing a stock engine or building a high-performance street machine, this gasket provides the reliability required for demanding environments.
