The QP2000 cast iron “Quiet Performer” header set for big block Chevy engines overcomes limitations of tube-style headers in both fit and in its ability to produce performance 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 power steering box.
Sanderson’s Cast Series header incorporates individual runners to separate 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 by D-Shaped technology, first used by GM on their HO (High Output) cylinder heads. The result is an exhaust header that improves torque and power at every RPM range.
Comes with all hardware necessary for installation.

Our Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. To meet high standards of quality, We apply a multi-layer inside and outside aluminized ceramic coating in-house and then polish 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.
