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! Comes with all hardware necessary for installation. Fits 1968-Up Nova, 1967-69 Camaro/Firebird, Corvette. Features a D-Port design with cast-in anti-reversion baffling, premium casting materials, thick flange area for optimum sealing, patented flange design which requires NO gaskets, tightest fitting header available anywhere, and it is made in the USA! Also includes the header bolt set and angle collector reducer set. Our Aluminized Ceramic Coating is available and RECOMMENDED on all Sanderson Headers. We apply a multi-layer inside and outside silver ceramic coating in-house to meet our high standards of quality, and polish the coated header to a high luster. This coating provides aerospace and military technology to your vehicle to control the heat in your engine bay, improve cylinder scavenging of exhaust gases, and increase the longevity of your header investment. Copper Collector Gaskets are recommended for all Sanderson headers. Sanderson Headers do not include collector bolts due to our customers' wide range of preference. We do offer a collector bolt set that features Grade 8 Bolts with Locking Nuts. 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. Limited 5-year warranty.
