The SBC Crossover Headers 1-3/4 from SCHOENFELD are purpose-built exhaust manifolds engineered for small-block Chevy engines seeking improved scavenging and flow efficiency. These conventional crossover headers are the go-to choice for street machines, race vehicles, and high-performance builds where extracting every horsepower from your SBC matters. Whether you're rebuilding a classic hot rod, preparing a weekend racer, or upgrading a performance street engine, quality headers form the foundation of any serious exhaust system.
These headers feature 1.75-inch primary tubes that optimize exhaust gas velocity and scavenging characteristics across the RPM range, flowing into a 3.5-inch collector for efficient consolidation before the rest of your exhaust system. Constructed from heavy-duty steel with a professional black paint finish, the SBC Crossover Headers deliver durability and corrosion resistance under sustained heat cycles. The package includes all necessary gaskets and hardware for bolt-on installation, eliminating the need to source additional components. The crossover design routes exhaust from each bank through a unified collector, enhancing cylinder-to-cylinder scavenging and providing a cleaner engine bay appearance compared to traditional side-exit manifolds.
Small-block Chevy platform owners—from 265 to 400 cubic-inch displacement—benefit most from this upgrade, particularly those prioritizing both performance gains and installation simplicity. The pair configuration allows seamless integration into existing exhaust plumbing, whether feeding a traditional muffler system or a modern high-flow setup. These headers excel in applications where underhood clearance is manageable and you want straightforward bolt-on installation without custom fabrication. Gaskets and hardware inclusion means installation can proceed without delay; simply confirm fitment with your specific engine block configuration and intake manifold design before ordering.
