Exhaust Gasket SBC w/ Stahl/Hooker Headers

The REMFLEX Exhaust Gasket SBC w/ Stahl/Hooker Headers (MPN 2040) is a precision-engineered gasket set designed for Small Block Chevy engines running Stahl 7-bolt or Hooker header configurations. This pair of graphite gaskets seals the critical 1.937-inch round port interface between the exhaust header and cylinder head, preventing exhaust leaks that compromise engine efficiency, increase noise, and allow unburned hydrocarbons to escape the combustion chamber.

REMFLEX gaskets are built from a high-temperature graphite composite that handles sustained exhaust temperatures without degradation, thermal cycling stress, or gasket creep over extended service intervals. Unlike soft-metal or composite gaskets that compress over time and lose sealing integrity, graphite maintains its dimensional stability across repeated heating and cooling cycles—critical for street, off-road, and competition applications where engine load and temperature vary constantly. The gaskets are engineered for the specific bolt pattern of Stahl headers, ensuring accurate alignment with the mounting surface and even clamping pressure across both cylinder heads.

This gasket set is suited for engine builders, restoration shops, and serious enthusiasts performing SBC header installation or replacement. Whether you're upgrading to high-flow Stahl or Hooker headers, diagnosing a pre-existing exhaust leak, or rebuilding a classic or performance engine, proper gasket selection matters—incorrect or degraded gaskets introduce vacuum leaks that throw off air-fuel ratios and create rough idle or starting issues. The lightweight 0.5-pound pair installs quickly and requires no modification or custom fitting.
