    With Hedman's guaranteed fit and lifetime warranty, how can you go wrong with these headers? Most are fabricated from 18-gauge steel with mandrel bent primary tubes and 1/4" flanges; some utilize thicker 14-gauge or 16-gauge tubing with 3/8" flanges. The black paint Hedman applies to uncoated headers is not high-temperature; it is pre-installation protection only. For the ultimate protection from the elements, click the following link to view Hedman's own HTC Hi-Tech Coated Headers.

    JEGS Easy Kits are designed by JEGS Professionals to help you get all the performance parts you need.

    Will these work on my static dropped 1966 1000 series GMC with the 250? I used a 2.5” drop spindle, 3” drop springs in Front and an axle flip in the rear.

    These long tube headers are probably to low for your lowered application.

    will these fi1 a 1963 GMC k1000 with the GM 305ci 5L big block V6?

    Asked by: Bessie
    No, this will not fit your V6 application.
