The 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.

Our 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 our 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.

There are other benefits to our Cast Series header. Because they are 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 the most popular header for small block 55-57 Chevy applications!

NOTE: Does not fit Vortec cylinder heads.

Comes with all hardware necessary for installation.

    Yes, it will fit the engine. The only concern would be the chassis that the engine is in.

    On the GM heads, yes, the QP1000 should work as long as the cylinder heads use a common plug location and angle.

    In a '67 Corvette with the 327, yes---as long as it is using standard straight plug cylinder heads and not something newer (such as Vortec for example).

    Installing a small block 383 with Dart heads in a 1967 Chevy Nova with a 10 year old Heidts sub frame, do you know what Sanderson headers will work?

GENERAL NOTES:

  1. Sanderson Headers are NOT emissions legal on pollution-controlled motor vehicles. It is the purchaser's responsibility to verify local regulations for compliance.
  2. Wrapping your Sanderson Headers with ANY thermal tape voids your header warranty. The best thermal protection for your headers is our Aluminized Ceramic Coating that is available for every Sanderson Header.

Limited 5 Year General Warranty

Sanderson Street Rod Headers strives to supply our customers with the highest quality parts and service available in the street rod industry. In keeping with this, we warrant and will repair or replace, at our option after inspection in our facility, any of our products which are found by us to have failed due to defects in either material or workmanship.  This warranty is activated by the return of the Warranty Card enclosed with every pair of headers, and is effective for FIVE YEARS * from the date of purchase as indicated on the original invoice.

This Warranty does not cover products that fail due to improper motor tuning, alteration, disassembly, or damage caused by racing, misuse, neglect, abuse, improper installation and/or accident, or when used on applications for which they were not designed or approved. We are specifically not responsible for the costs of removal, installation, transportation, destruction of other components, inconvenience, loss of time, or other personal damages, or for any other associated costs including the application of aftermarket coatings applied by others. Sanderson Street Rod headers shall not be liable for any and all consequential damages occasioned by the breach of any written or implied warranty pertaining to this sale in excess of the purchase price of the product(s) as found on the original invoice.

WRAPPING HEADERS WITH THERMAL TAPE VOIDS WARRANTY.

 

* Extremely compact header designs which locate the collector in close proximity to the exhaust ports are very sensitive to engine tuning. Improper air/fuel mix or timing of ignition and/or valvetrain can cause early failure due to excessive heat. For this reason, part numbers CC2 and CC3 are offered with a two-year Warranty period only. All other Warranty conditions apply.
