SBC Street Stock Headers 1-5/8 - 1-3/4

The Schoenfeld SBC Street Stock Headers 1-5/8 - 1-3/4 (Part No. 185V) are purpose-built exhaust headers designed for small block Chevy engines in street stock racing and classic muscle car applications. These headers feature stepped primary tubes ranging from 1-5/8 to 1-3/4 inches, optimizing exhaust scavenging across the RPM band while maintaining street-friendly power delivery. The 3-inch collector provides efficient gas merging and transition to the exhaust system, making this a proven solution for GM A-Body, F-Body, and G-Body vehicles running small block Chevy mills.

Manufactured in steel and finished in durable black paint, these Schoenfeld headers are built to withstand the heat cycling and vibration of sustained street and track use. The stepped primary design addresses a fundamental reality in small block Chevy performance: no single tube diameter optimizes flow across the entire power band. By transitioning from smaller to larger tubes, these headers maintain velocity in the primary runners where scavenging matters most, while the larger sections prevent backpressure buildup at higher RPMs. Each pair includes all necessary gaskets and mounting hardware, eliminating the need for separate purchases during installation.

Street stock competitors and classic car enthusiasts will appreciate the proven track record of Schoenfeld headers in this application. The 185V model addresses the specific needs of small block Chevy owners seeking improved exhaust flow without exotic tube angles or non-standard collector designs that complicate installation or create fitment issues on original chassis. At 27 pounds per pair, these headers represent a practical performance upgrade that delivers measurable gains in breathing and throttle response, particularly in naturally aspirated engines operating between 4,000 and 6,500 RPM where street stock competition typically occurs.
