BAE Copper Head Gasket 4.470 x .080

The BAE Copper Head Gasket 4.470 x .080 is a premium cylinder head gasket engineered for high-performance Mopar 426 Hemi engines. This gasket seals the critical interface between the cylinder head and engine block, preventing coolant and combustion gas leakage while maintaining compression integrity. Built by SCE Gaskets—a trusted name in racing and performance engine sealing—this copper head gasket is designed for builders and enthusiasts who demand reliability under extreme conditions.

Constructed from durable copper material, this head gasket features a 4.470-inch bore diameter and 0.080-inch compression thickness, specifications matched precisely to AJPE and BAE cylinder head applications. Copper construction delivers superior thermal conductivity and conformability compared to conventional materials, allowing the gasket to maintain a consistent seal across varying cylinder pressures and temperature cycles. The 0.080-inch thickness is engineered to optimize compression ratio and combustion chamber volume for maximum performance potential in high-horsepower Hemi builds.

This gasket is ideal for engine builders, restorers, and drag racing competitors working on 426 Hemi platforms where OEM reliability must be exceeded. Installation requires proper torque sequencing and head surface preparation to ensure optimal sealing performance. When paired with quality fasteners and correct assembly procedures, the BAE Copper Head Gasket provides the durability needed for street, strip, and show applications. Each unit ships ready for immediate installation on compatible AJPE and BAE Hemi cylinder heads.
