Brodix Spread Port Gaskt D Shape

The Brodix Spread Port D-Shape exhaust header gasket by Schoenfeld is a precision-engineered component designed for small-block Chevy engines requiring reliable high-temperature sealing at the exhaust manifold. With a steel-core graphite construction and port dimensions of 1.650 x 1.700 inches, this gasket delivers the thermal stability and compression resistance needed for consistent exhaust system performance across a wide range of engine configurations and operating conditions.

The steel-core graphite composition provides superior heat resistance compared to standard gasket materials, maintaining integrity under the extreme temperatures generated in the exhaust manifold environment. The D-port profile conforms precisely to small-block Chevy exhaust port geometry, ensuring a tight seal that prevents exhaust leakage and maintains back-pressure efficiency. This gasket is manufactured to exact tolerances, minimizing the risk of blow-out or degradation over extended use, whether in street applications or higher-load scenarios.

Buyers rebuilding or servicing small-block Chevy engines—from muscle car restorations to modern performance builds—depend on this gasket to seal the critical interface between the cylinder head and exhaust manifold. A failed header gasket can result in exhaust leaks, reduced engine efficiency, and potential heat damage to surrounding components. The Brodix Spread Port D-Shape gasket is a direct-fit replacement that restores proper sealing without modification, making it an essential component for any exhaust system overhaul or engine rebuild involving small-block Chevy platforms.
