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!

NOTES:

• The QP1000 fits straight plug, standard bolt pattern, standard port location cylinder heads.
• Does NOT fit Vortec-style cylinder heads (Please review the “Vortec-Style Heads” information tab)
• Not compatible with BluePrint cylinder heads. (BluePrint heads are based on GM Vortec plug locations)
• Fits 1968-Up Nova, 1967-69 Camaro/Firebird, Corvette, Tri-Five, and many other applications!

Includes all hardware necessary for installation.

FINISH:

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.

The Chevy 409 engine started the muscle car horsepower race of the ’60s, and it is making a comeback. The CC409 is designed to fit tight to the block and will work in street rod chassis and many other cars and trucks without a cross-member under the center of the motor.
