BBM Titan Copper Head Gasket 4.380 x .043

The BBM Titan Copper Head Gasket 4.380 x .043 from SCE Gaskets is engineered for high-performance engine builds where reliability and precision sealing are non-negotiable. Whether you're assembling a turbocharged stroker, big-block platform, or endurance racing engine, this copper head gasket delivers the thermal stability and sealing integrity that serious builders demand. The 4.380-inch bore diameter positions this gasket for large-displacement applications where standard gaskets fall short of performance requirements.

Constructed from premium copper with a .043-inch thickness, the BBM Titan gasket provides superior heat transfer away from the combustion chamber while maintaining a robust seal under extreme cylinder pressures and temperature cycles. The copper construction resists blow-by and deformation better than traditional steel-core designs, making it ideal for forced induction, nitrous oxide systems, and high-boost applications. The precision-machined bore and fire-ring geometry ensure consistent compression and minimal gasket erosion, even when push-rod clearance is tight or head surfaces have been extensively ported and polished.

This gasket suits big-block Chevrolet, Ford, and Chrysler platforms, as well as custom billet and aftermarket block combinations where bore sizing exceeds 4.310 inches. Installation requires proper head surface preparation, correct torque sequences, and use of quality fasteners to maximize gasket performance. Builders working with aggressive cam timing, elevated boost levels, or multi-event competition engines will appreciate the durability and sealing consistency that SCE's Titan series delivers across extended engine run-in periods and high-rpm operation.
