<p>Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing LONG and MID-LENGTH tube headers for Chevy trucks for nearly as long. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your Small Block Chevy exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.</p><p>These uncoated, LONG-TUBE headers are covered by CARB E.O. (Executive Order) #D167-33, making them 50-State Legal for the vehicles listed on the arb.ca.gov website. They fit a wide range of 1967-1987 2WD & 4WD Chevy/GMC 1/2 Ton and 3/4 ton trucks, Blazers and Suburbans <i>(check the application listings for exact fitment)</i>, powered by a Small Block Chevy engine <i>(with A.I.R. System)</i>., and provide additional clearance for clutch shaft clearance issues, when the cross shaft is located under, or behind the rear, driver side exhaust port. The smooth 1-5/8 in. tube design provides ample exhaust flow to let your truck's 283-400 SB Chevy engine breathe easy, and produce maximum horsepower and torque.</p><p> These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. For protection against the element and lower under hood temperatures, these headers are also available with a silver or black ceramic-metallic finish.</p><p>Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.</p><p>Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.</p>
