The QP2000 provides excellent steering clearance, even for 1955-1957 Chevrolet applications using the Saginaw 605 power steering box.<\/p>\n<p>Sanderson&#8217;s Cast Series header incorporates individual runners to separate 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 by D-Shaped technology, first used by GM on their HO (High Output) cylinder heads. The result is an exhaust header that improves torque and power at every RPM range.<\/p>\n<p>Comes with all hardware necessary for installation.<\/p>\n<p><strong>SPECIFICATIONS:<\/strong><\/p>\n<p>Engine: Big Block Chevy 395-454, 502<br \/>\nPrimary Diameter: 1-7\/8&#8243;<br \/>\nCollector Diameter: 3&#8243;<\/p>\n<p><strong>FEATURES:<\/strong><\/p>\n<ul>\n<li>16-Gauge Primary and Collector Tube Thickness<\/li>\n<li>3\/8&#8243; Thick Flange<\/li>\n<li>Patented Flange Design Requires NO Gaskets<\/li>\n<li>Tightest Fitting Header Available Anywhere!<\/li>\n<li>Made in the USA<\/li>\n<\/ul>\n<p><strong>INCLUDES:<\/strong><\/p>\n<ul>\n<li>Header Bolt Set<\/li>\n<li>Collector Reducer Set<\/li>\n<\/ul>\n<p><strong>FINISH:<\/strong><\/p>\n<p>Our <strong>Ceramic Coating<\/strong> is recommended for every vehicle application and is the default finish selection choice above.
