Exhaust Gasket SBC 23 Degree

The Exhaust Gasket SBC 23 Degree from Beyea Custom Headers is a precision-engineered seal designed for small-block Chevrolet engine builders and performance enthusiasts who demand reliability in high-heat exhaust applications. This gasket serves as a critical barrier between the cylinder head and exhaust manifold or custom header, preventing exhaust leaks that degrade engine efficiency and create unwanted noise. Whether you're building a street engine, race platform, or restoring a classic with modern performance upgrades, this component ensures a tight, lasting seal under extreme temperatures and pressure cycles.

The 23-degree specification refers to the gasket's combustion chamber angle alignment, matching the precise geometry of SBC cylinder head ports to guarantee proper sealing without gaps or misalignment. Beyea Custom Headers manufactures this gasket with materials designed to withstand high exhaust temperatures while maintaining resilience against thermal cycling stress. The compact footprint (measuring 3.9 x 0.55 x 19.45 inches) fits standard SBC header flanges, and the minimal weight of 0.12 lbs ensures no impact on engine bay balance or performance tuning.

Quality gasket construction prevents blow-by, maintains back-pressure integrity, and eliminates the need for repeated gasket replacement due to premature failure or degradation. SBC engine builders, hot rodders, and mechanics performing header installations will find this gasket essential for achieving optimal performance and reliability in their projects.
