Gasket SBC SB2

The Schoenfeld Gasket SBC SB2 is a precision exhaust header gasket engineered for small-block Chevrolet applications. This steel-core graphite gasket features a 1.740 x 1.550 inch square port design and is built to withstand high exhaust temperatures and pressure cycles inherent to modern and classic SB2 engine builds. Gasket selection directly impacts exhaust sealing integrity, preventing costly leaks and heat loss that compromise engine efficiency and longevity.

The steel-core graphite construction combines the durability of embedded steel with the thermal stability and conformability of graphite facing material. This layered approach accommodates the micro-surface variations between header and cylinder head while resisting blow-by across multiple heating cycles. The square port configuration matches OEM and most aftermarket header designs intended for small-block Chevrolet engines, ensuring proper alignment and consistent sealing pressure throughout the gasket's service life.

This gasket is essential for engine builders, hot rodders, and performance enthusiasts performing header installation, replacement, or restoration work on Chevrolet small-block platforms. Whether supporting a stock rebuild, a naturally aspirated performance upgrade, or a complete engine swap, the Schoenfeld SBC SB2 gasket provides the reliable port sealing required to maintain compression, prevent exhaust leaks, and reduce vibration noise from header rattle. Individual gasket sales allow builders to replace compromised seals without purchasing complete header assemblies.

Schoenfeld Headers holds a recognized position in the exhaust systems market for header manufacturing and component quality. The Gasket SBC SB2 represents the OEM-equivalent gasket standard for Chevrolet small-block header applications, making it a dependable choice when precision gasket replacement is required for leak-free exhaust sealing.
