• Construction: Embossed stainless steel outer layers with a central shim
• Installation: Requires less clamp load, reducing bore distortion and conforming to the sealing area

Fits 1990-2001 Honda CR-V and Prelude models equipped with B-series non-VTEC blocks (B18A/B) utilizing a VTEC cylinder head conversion.

Engineered specifically for the unique demands of "LS/VTEC" or "B20/VTEC" hybrid engine builds, this Cometic Multi-Layer Steel (MLS) head gasket provides a superior seal without the need for additional sealants. The 81.5mm bore and 0.030-inch compressed thickness are ideal for high-output naturally aspirated or forced induction setups. Each gasket features multiple layers of embossed stainless steel to provide a strong, rebound-capable seal that resists the shearing forces common between aluminum heads and cast iron blocks.

The outer layers are finished with a Viton rubber coating, a fluoroelastomer material capable of withstanding temperatures up to 250°C (482°F). This advanced coating ensures a reliable seal across various surface finishes and load conditions, while the uncoated stainless steel shim layer allows for precise thickness tolerances. By requiring less clamp load than traditional gaskets, this MLS design helps minimize bore distortion during final assembly.
