Cometic C4191-040 Honda B-Series VTEC Hybrid MLS Head Gasket 82mm

The Cometic C4191-040 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for Honda B-Series hybrid engine builds combining a VTEC cylinder head with a non-VTEC block. This premium gasket features a .040" (1.0mm) compressed thickness and an 82mm bore diameter, making it ideal for mild performance builds and engine swaps requiring precise sealing between mismatched head and block combinations.

Key Features:

• Multi-layer steel construction provides superior sealing and durability under high-stress conditions
• .040" compressed thickness allows for precise compression ratio tuning
• 82mm bore diameter accommodates standard B-Series engine configurations
• Engineered specifically for VTEC head to non-VTEC block hybrid applications
• Embossed stainless steel layers with Viton rubber sealing beads ensure exceptional combustion sealing
• Resistant to extreme temperatures and pressures in performance applications

Cometic MLS gaskets are manufactured with precision-machined embossments that concentrate sealing pressure around critical areas like combustion chambers and fluid passages. This design allows the gasket to rebound and maintain torque loads better than traditional composite gaskets, making it an excellent choice for turbocharged, supercharged, or high-compression B-Series hybrid builds.
