Gasket SBC Spread Port 2in Down Nozzle Lite

The Schoenfeld Gasket SBC Spread Port 2in Down Nozzle Lite is a precision exhaust header gasket engineered specifically for Small Block Chevy applications with spread-port intake manifold configurations. This steel-core graphite gasket features a 1.700-inch diameter port design optimized for the typical Small Block Chevy exhaust port spacing, delivering reliable sealing at the critical interface between the cylinder head and exhaust manifold.

The steel-core graphite construction combines the durability and thermal stability of a reinforced steel carrier with graphite facing that conforms precisely to mating surfaces. This material pairing resists compression set under sustained heat exposure, preventing exhaust leaks that would otherwise develop as the engine thermally cycles between idle and wide-open throttle conditions. The 2-inch down nozzle configuration accommodates typical Small Block Chevy manifold designs, ensuring proper fit without modification. Weighing just 0.11 pounds, the gasket maintains minimal thermal mass while providing the structural integrity needed for reliable long-term sealing in stock and modified Small Block engines alike.

This gasket is essential for anyone rebuilding or servicing a Small Block Chevy engine, whether for street driving, weekend cruising, or track duty. Exhaust leaks bypass combustion efficiency, reduce backpressure consistency, and allow exhaust gases to escape before reaching the exhaust system—outcome that degrades both performance and emissions control. Using a properly-sized OEM-style gasket like the Schoenfeld spread-port design eliminates guesswork and ensures the gasket will seat correctly across the entire port diameter on the first installation.

Schoenfeld is recognized within the Small Block Chevy performance community for manufacturing gaskets that match OEM port dimensions and configurations. The Lite designation reflects an optimized weight-to-performance ratio, making it ideal for builds where thermal response and weight savings matter without sacrificing sealing reliability. Sold as a single gasket per package.
