SBC Exhaust Gasket 1-7/8in D

The Schoenfeld SBC Exhaust Gasket 1-7/8in is a steel core graphite exhaust header gasket engineered for small block Chevy engines requiring reliable thermal and pressure sealing at the manifold interface. This gasket is designed to handle the demanding duty cycle of high-performance and racing applications where engine vibration, thermal cycling, and exhaust gas pressure demand precision engineering and material durability.

Rated for a 1.890-inch round port configuration, the gasket combines a steel core substrate with graphite facing to withstand exhaust temperatures and maintain compression integrity across repeated heat cycles. The steel core prevents deformation under pressure while the graphite facing conforms to the mating surfaces of the header and cylinder head, minimizing exhaust leakage. With a compact weight of 0.11 lbs and minimal thickness, this single gasket installs quickly without adding dead space or complexity to the manifold assembly.

Engine builders, hot rod shops, and serious enthusiasts working with small block Chevy platforms—whether for street performance, track duty, or restoration work—rely on Schoenfeld gaskets to maintain clean, leak-free header seals across thousands of miles of hard driving. The 1-7/8 inch port diameter is the industry standard for SBC applications and ensures drop-in compatibility with aftermarket and OEM headers designed to that specification. This is an essential consumable for any manifold installation or rebuild.
