    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.

    69230 is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from On my 1977 k20 manual transmission they worked perfect just remember to buy shorty plugs
    Date published: 2017-06-23
    Rated 5 out of 5 by from Great fit on my 1972 4x4 blazer 4 speed stick. Fits great! Not to close to the leaf spring shackles. Perfect position on missing the transfer case. Had to ding in the number 7 piston tube to miss the clutch z bar but just a really small amount. If buying 3 inch collectors and running 3 inch all the way don't forget to buy 3 inch ball socket adapter because they come with 2.5 reducers.
