HEADER,BB MOPAR,1 7/8,67-74,LONG TUBE,3,BLACK

Brand New Hooker Competition Long Tube Headers, Black Ceramic Coated, 3" Collectors, 1.875" Primary Tubes, 383-440 Chrysler Big Block, Compatible with 1966-1974 Charger (Part #5903-3HKR)

Hooker Competition headers are designed for the value-conscious buyer who is running either a stock or mildly-modified engine. They are made of durable 16-gauge mild steel tubing and utilize a long transition collector to reduce back pressure and increase exhaust flow.

A perfect sealing surface is assured with the 5/16" machined flanges with welded O-ring seals. Experience has proven that this flange size is ideal to maintain header integrity and be pliable enough to seal each exhaust port. Tubing is mandrel-bent to maintain metal strength and provide consistent tube diameter at radii to maximize performance.

Note: Does not include reducers. Will not fit motors equipped with air injection pump without modification.

Note: Bolts to the popular B-S heads. However, because the exhaust port centerline on these heads is 5/8" higher and 3/8" out from the engine centerline compared to stock heads, some header modifications will be required for installation. Custom header applications will be required for B-1 heads due to angled spark plug locations.

Note: Breaking in an engine with ceramic-coated headers will result in damage to the coating and will void all warranties. These headers require several heat cycles to fully cure before they will withstand extreme heat.
