The Sanderson QP1000 cast iron "Quiet Performer" header 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 QP1000 provides excellent steering clearance, even for Tri-5 vehicles 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.
Because the QP1000 is more compact than tubular headers, they provide more clearance for steering, accessories, and other chassis and engine components. They weigh less than factory exhaust, and they look a whole lot better! This is Sanderson's most popular header for small block 55-57 Chevy applications!
The QP1000 will fit standard pattern, standard port location cylinder heads, and some GM angle plug heads.

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.
