The Sanderson QP2000 cast iron "Quiet Performer" header for big block Chevy engines overcomes limitations of tube-style headers in both fit and in its ability to produce gains in both low end torque and high end horsepower. The QP2000 provides excellent steering clearance, even for 1955-1957 Chevrolet applications using the Saginaw 605.
Sanderson's Cast Series header incorporates individual runners to separate exhaust pulses, with cast 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 by their D-Shaped technology, first used by GM on their HO (High Output) cylinder heads. The result is exhaust headers that create more torque and power at every RPM range.
There are other benefits to Sanderson's Cast Series header. Because they are more compact than tubular headers, they provide more clearance for stock, manual, 605, or rack and pinion steering setups, accessories, and other chassis and engine components.

Sanderson's Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. To meet high standards of quality, Sanderson applies a multi-layer inside and outside aluminized ceramic coating in-house and then polishes the coating to a high luster. This aerospace and military-grade technology adds excellent protection to your headers, while offering the benefit of thermal control in your engine bay. It also improves cylinder scavenging of exhaust gases, and increases the longevity of your header investment.
