Sanderson Headers QP2000-SEC Features:

The QP2000 cast iron “Quiet Performer in. header set for big block Chevy engines overcomes the limitations of tube-style headers in fit and its ability to produce performance gains in low-end torque and high-end horsepower. The QP2000 provides excellent steering clearance, even for 1955-1957 Chevy 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 gases from being drawn back into the cylinder during valve timing overlap (when both intake and exhaust valves are open). D-Shaped technology, first used by GM on their HO (High Output) cylinder heads, significantly improves cylinder scavenging. The result is an exhaust header that improves torque and power at every RPM range.

NOTE: The QP2000 is compatible with factory Z-bar, manual transmission applications if the rear pivot ball mounting location is used (see image). Otherwise, a hydraulic clutch conversion is required. Comes with all hardware necessary for installation.

FINISH:

• Sanderson 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.

Installation Notes:

The Patented Leak-Free Design on Sanderson Headers provides the only leak-free flange design on the market … Do Not Attempt To Use Flange Gaskets! The raised flange on tube-style Sanderson Headers will buckle the gasket during tightening and cause a leak! It is only OK to use a header gasket on the cast-series header sets (QP1000 and QP2000) Sanderson Headers are NOT emissions legal on pollution-controlled motor vehicles. It is the purchaser’s responsibility to verify local regulations for compliance. Wrapping Sanderson Headers with ANY thermal tape voids the header warranty.

Emissions Note:

This part is only legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles or on vehicles used solely for the purposes of closed competition racing.
