QP2000 Cast-Series Header Set, Big Block Chevy

SamSDHadmin — Mon, 05 Jun 2023 04:53:54 +0000

The QP2000 cast iron “Quiet Performer” 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 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 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:

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.

QP1000 Cast-Series Header Set, Small Block Chevy

SamSDHadmin — Mon, 05 Jun 2023 04:11:43 +0000

The QP1000 cast iron “Quiet Performer” header set overcomes some limitations of tube-style headers while providing a tight fit and producing gains in both low-end torque and high-end horsepower. The QP1000 provides excellent steering clearance, even for Tri-5 (1955-57) Chevy cars using the Saginaw 605 power steering gear.

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.
