SBC ISC Titan Copper Hd Gasket 4.155 x .050

The SBC ISC Titan Copper Head Gasket 4.155 x .050 is a premium cylinder head gasket engineered for small-block Chevy engines requiring reliable combustion sealing and consistent compression retention. SCE GASKETS has designed this copper gasket specifically for builders and machine shops seeking maximum durability and performance in high-horsepower and nitrous-assisted applications where standard gaskets fall short.

The 4.155-inch bore specification matches common small-block Chevy cylinder head configurations and provides the sealing surface area necessary for precision-ported or oversized valve packages. The .050-inch compression thickness is a critical dimension that directly affects combustion chamber volume and final compression ratio—a thinner gasket raises compression slightly compared to stock thickness, an important consideration when tuning for peak performance. Copper construction provides superior heat transfer away from the combustion chamber and resists blowby at elevated boost levels and detonation conditions that compromise conventional composite gaskets.

This gasket is specified for engine builders assembling competition carbureted engines, fuel-injected street performance builds, and nitrous oxide systems where combustion pressures exceed stock limits. The Titan line from SCE represents the choice for builders who need repeatable sealing across multiple dyno sessions and weekend racing events. Proper installation requires appropriate head bolt torque sequencing and clean deck surfaces to achieve optimal gasket conformance and prevent mid-season failures.

Small-block Chevy engine platform gaskets demand precise fitment and material selection. The ICS Titan copper gasket is engineered to outperform stock OEM gaskets in modified engines while maintaining the reliability expected in street-driven vehicles where downtime is not acceptable. Each gasket is sold individually.
