    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
    • Made in USA

    Rated 4 out of 5 by from Supercharger project on 1984 k-10 I was looking for an 1 3/4 inch tube header. These headers do look nice but I'm not sure the design is ideal. I had to clearance a few of the bolts just to get a box end wrench or socket on them. The design of the header tubes makes it difficult to bolt up the headers. They also are really close the front, lower, rear spring shackles and I had to clearance the left side header flange and, as a word of advice, make sure the lower shackle spring bolt is head to the inside. I'm not sure if there will be enough clearance on the passenger side yet or not since I have not ran the truck. The right header is farther back at the collector than the drivers side. I had to rework the rest of the exhaust to make everything fit back up correctly. Overall they are nice heavy headers and I don't believe they will be overall any long term issues. Not an afternoon project. The best way is to bring these headers from underneath to install. They are designed for that method unlike most cheaper headers. I hope this helps and overall I would recommend if you have some skills.
