Hedman Hedders - 68610
Headers - Street - 1.75 in Primary - 3 in Collector - Steel - Black Paint - Big Block Chevy - GM A-Body / B-Body / F-Body / X-Body 1965-81 - Pair
Standard Uncoated Headers; 1-3/4 in. Tube Dia.; 3 in. Coll.; Mid-Length Design
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 passenger cars for decades. 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 Big Block Chevy exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.
These MID-LENGTH headers fit Big Block Chevy V8 powered, 1967-81 Chevy Camaros; 1968-1977 GM A-Body vehicles (Chevy Chevelle, El Camino, Monte Carlo, Olds Cutlass, Pontiac Grand Prix); '68-79 Chevy II and Nova. These headers are also compatible with other 1965-74 passenger cars from Chevrolet. The smooth 1-3/4 in tube design provides ample exhaust flow to let your 396-454 BB Chevy engine breathe easy, and improve horsepower and torque over stock manifolds.
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 underhood temperatures, these headers are also available with a silver or black ceramic-metallic finish.
Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.
Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.
