    Do It Once, Do It Right

    Hedman Elite Headers are the best you can buy. They have thicker flanges, stronger tubing, and thermal coating to withstand full-throttle thrashing and torturous towing. Their extreme-duty construction protects against burnout and exhaust leaks caused by the excessive heat and vibration of high-performance applications. Elite Headers outlast and outperform ordinary headers. All Hedman street headers are made in the USA with a 5-year coating warranty and lifetime product defect warranty.

    Note: Installing coated headers on an engine during the break-in period will cause discoloration. It is recommended that the factory manifolds or an old set of headers are used while breaking in an engine.

    Features
    • Hefty 3/8" flanges
    • Shorty or full-length design
    • Thick wall 14-gauge primary tubes
    • Built to withstand tough applications
    • HTC thermal coating with 5-year warranty
    • Lifetime warranty against manufacturing defects

    JEGS Easy Kits are designed by JEGS high performance racing professionals to help you get all the performance parts you need for your race car, hot rod or truck.

    69820 is rated 4.2 out of 5 by 5.
    Rated 5 out of 5 by from Great The headers fit great on my 88 Fleetwood p30 chassis motor home, have thick flanges and so far my motorhome runs much better and has no leaks.
    Date published: 2017-03-26
    Rated 5 out of 5 by from ordered for an ongoing project but first blush they are exceptional. They look great, came with all instillation hardware and bolts. I am looking forward to getting this together.

    Rated 5 out of 5 by from Functioned as advertised I installed a set of Hedman 69820 in my 1976 Chevrolet, C20 , ZZ502/502 engine with standard 1976 BB/SB Starter motor and 700R4 transmission. They fit perfect in the truck but as advertised the header flange did make contact with the top of some head bolts requiring a little grinding. so far I have only had to re-torque the header bolts once due to the improved gaskets that came with the headers. As advertised the coating on the headers did discolor at some of the bends due to the heat the NEW 502 can develop. Due to the packaging the headers came out of the box damaged , the machined edges on the flanges scratched and gouged the tubes near the collector. but JEGS gave me some money back for repairs.

    Rated 1 out of 5 by from Rusted Bought several years ago. Started rusting right out of box. Ceramic coating garbage. Not worth extra money for costing. Looked great at first except mechanic pointed out specks of rust around weld areas. No I dont recommend the cermanic coating. Maybe I got a bad pair. Not a problem with Jegs!
