Cometic MLS Head Gasket 84.5mm Bore .040" Thick for 1988-2001 Acura/Honda B-Series LS/VTEC Hybrid C4241-040

Fits select 1988-2001 Acura Integra, Honda CR-V, and Honda Prelude models with B18 or B20 non-VTEC blocks and VTEC cylinder heads.

The Cometic Multi-Layer Steel (MLS) Head Gasket is the professional choice for high-output "LS/VTEC" or "CRV-TEC" hybrid engine builds. This gasket is specifically designed to seal the junction between a B18 or B20 non-VTEC block and a VTEC cylinder head without the need for copper spray or additional sealants. The multi-layer stainless steel construction provides superior rebound characteristics and corrosion resistance, while the embossed outer layers are coated on both sides with Viton—a fluoroelastomer rubber capable of withstanding temperatures up to 250°C (482°F).

By utilizing stainless steel, this gasket maintains its integrity under the high shearing forces generated by differing thermal expansion rates between the head and block. The design also facilitates even load distribution across the sealing area, requiring less clamp load and reducing cylinder bore distortion compared to traditional composite gaskets.
