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.

Precision Sealing for Overbored B-Series Engines

Maximize your engine's potential with the Cometic 81.5mm .030 inch MLS Head Gasket. Designed for overbored B18A/B non-VTEC engines, this high-performance gasket features a thinner .030 inch profile to help increase static compression ratios, making it an ideal choice for naturally aspirated performance builds. The multi-layer steel construction provides the structural integrity needed to handle increased cylinder pressures.

Technical Specifications

  • Bore Size: 81.5mm for overbored engines.
  • Compressed Thickness: .030 inch for optimized compression.
  • Construction: Multi-layer stainless steel for maximum strength.
  • Coating: Viton rubber coating for superior micro-sealing.
  • Compatibility: Perfect for aluminum-to-iron or aluminum-to-aluminum mating surfaces.

The Viton-coated outer layers offer excellent heat resistance and rebound properties, ensuring a leak-free seal even after multiple heat cycles. By eliminating the need for extra sealants, this gasket simplifies the assembly process while providing professional-grade reliability. Whether you are racing or building a high-output street machine, this Cometic gasket is a critical component for your build. Find all your engine sealing solutions at GGCRACING.
