Th e QP1200 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 QP1200 is designed with a rear exit to fit 1964-Up Chevelle, Malibu, and El Camino applications. The QP1200 also fits Chevrolet full size and various other street rod applications, including those using Chevelle suspension grafts.
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!
NOTE: Does not fit Vortec cylinder heads
Comes with all hardware necessary for installation.

NOTES:
 The Patented Leak-Free Design that Sanderson Headers offer you is the only leak-free flange design on the market ... Do Not Attempt To Use Flange Gaskets! The raised flange on the Sanderson Headers will buckle the gasket during tightening and actually cause a leak!- Sanderson Headers are NOT emissions legal on pollution-controlled motor vehicles. It is the purchaser's responsibility to verify local regulations for compliance.
- 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.
