SBC Crossover Header 602 Crate 1-5/8in

The Schoenfeld SBC Crossover Header 602 Crate 1-5/8in is a conventional crossover header system engineered specifically for small block Chevy engines in 602 crate configurations. This pair of headers features 1.625-inch primary tubes that converge into a 3-inch collector design, optimizing exhaust scavenging and flow characteristics for consistent power delivery across the RPM range. Supplied complete with gaskets and hardware, these headers are ready for bolt-on installation without additional fabrication.

Manufactured from steel and finished in durable black paint, the crossover design routes exhaust from both cylinder banks into a single collector, reducing backpressure and improving volumetric efficiency compared to traditional log-style headers. The 1-5/8 inch primary diameter is optimized for the displacement and intended operating range of 602 crate motors, which typically see service in club racing, bracket racing, and vintage competition environments where consistent performance and reliability take priority. The 3-inch collector provides adequate cross-sectional area to prevent restriction while maintaining scavenging benefits through the mid-range RPM band.

This header set addresses the needs of builders and racers working within spec-limited classes where engine platform and component selection are tightly regulated. The 602 crate engine, commonly mandated in specific racing classes, benefits from quality exhaust manifolding that minimizes thermal stress and supports reliable repeated use over a full racing season. The inclusion of mounting hardware and gasket sets eliminates sourcing delays and ensures proper fitment on first installation.

Schoenfeld headers are recognized in circle track and bracket racing communities for straightforward engineering and proven durability. The crossover configuration is standard practice in crate engine racing, where rule sets and cost control make these purpose-built systems the practical choice over custom fabrication.
