Sanderson Headers QP1000-SEC Features:

The QP1000 cast iron “Quiet Performer in. header set overcomes some limitations of tube-style headers while providing a tight fit and producing gains in both low-end torque and high-end horsepower. The QP1000 provides excellent steering clearance, even for Tri-5 (1955-57) Chevy cars using the Saginaw 605 power steering gear. The QP1000 Cast Series header incorporates individual runners to separate the engine’s exhaust pulses, with cast-in anti-reversion baffling to prevent spent gasses from being drawn back into the cylinder during valve timing overlap (when both intake and exhaust valves are open). Scavenging of the cylinders is significantly improved through D-Shaped technology, first used by GM on their HO (High Output) cylinder heads. The result is an exhaust header that creates more torque and power at every RPM range. Other Benefits: Because the QP1000 is more compact than tubular headers, it provides more clearance for steering, accessories, and other chassis and engine components. Cast using the highest-quality materials, the QP1000 is stronger and more reliable than the original factory exhaust, and it offers great looks, too! The QP1000 is Sanderson’s most popular header for small block 55-57 Chevy applications!
