    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.

    Rated 2 out of 5 by from Does not fit its application. I bought this for my 69 chevy C10 half ton, it seemed like the headers weren't even made for this truck. I would have had to cut 1-1/2" out of the top of my frame to make it fit. Instead I cut the tube and put a new pipe section in it. AND, the bolts they send won't go into the flanges without denting the pipes. All in all, I expected much more from Hedmann.

    Rated 5 out of 5 by from Great product easy to put on just had to remove starter on passenger side to put it on. Everything bolted up and it sounds great
