LS ISC Titan Copper LH Head Gasket 4.160 x .050

The LS ISC Titan Copper Left-Hand Head Gasket 4.160 x .050 from SCE Gaskets is a precision cylinder head gasket engineered for GM LS-series engine builds. This gasket features a 4.160-inch bore diameter and 0.050-inch compression thickness, delivering the exact sealing geometry required for LS engine blocks seeking maximum reliability and performance consistency across a wide range of racing, street performance, and rebuild applications.

SCE's Titan copper construction provides superior thermal conductivity and gasket crush strength compared to conventional composite materials, allowing the gasket to maintain a consistent seal under the elevated combustion pressures and temperature cycling common in turbocharged, supercharged, and high-rpm naturally aspirated LS engines. The .050-inch compression thickness is a proven specification for street and mild competition builds, balancing head gasket clamping force with reliable ring sealing.

This gasket is the choice for engine builders and LS enthusiasts rebuilding tired blocks, upgrading to modern cylinder heads, or assembling fresh powerplants for street cars, muscle cars, trucks, and weekend race vehicles. Proper head gasket selection is critical—incorrect bore diameter or compression thickness can result in combustion gas leakage, coolant intrusion, or oil weeping. Ensure you select the correct orientation for your engine configuration to achieve optimal performance.
