About Cometic Gasket

Heavy-Duty Sealing for Overbored B-Series Engines

When you overbore your B18A/B engine to 81.5mm, you need a head gasket that can handle the increased cylinder diameter while maintaining a perfect seal. The Cometic 81.5mm .051 inch MLS Head Gasket is the industry standard for high-performance Honda/Acura builds. Its multi-layer steel design is engineered to provide maximum sealing performance, preventing leaks and blown gaskets under high-boost or high-RPM conditions.

Technical Specifications

  • Bore: 81.5mm for overbored blocks.
  • Thickness: .051 inch compressed thickness.
  • Material: Multi-layer stainless steel.
  • Coating: Viton rubber for superior sealing and heat resistance.
  • Application: Non-VTEC B18A/B engines.

This gasket is designed to rebound and resist corrosion, making it the perfect choice for engines that see frequent track time or high-stress environments. The Viton coating ensures that even with the expansion and contraction of different engine materials, the seal remains intact. By choosing Cometic, you are choosing a product that has been proven on tracks worldwide. Ensure your engine build is reliable and leak-free for years to come.
