    2453 - Hooker Headers Competition Headers Chevy/GM Truck is rated 4.6 out of 5 by 10.
    Rated 5 out of 5 by from Truck breathes so much better Put these on my K20 and they immediately seemed to help performance. Plus gave my truck a great sound. Running a 350 with these headers into 3” thrush mufflers and 3” straight pipe dumping out right at the rear axles. Recommend wrapping them before install. Or get spark plug boots because these get hot! Fit was also fairly tight with the starter, but not too bad.

    Rated 5 out of 5 by from Hooker headers 85 chevy 305 Well constructed and great fit on 85 k10 manual transmission. Had to trim the corner of driver's side motor mount but everything else fit great. Gave me more performance on bottom end and sound great.
    Date published: 2020-04-25
    Rated 5 out of 5 by from 1971 Blazer K5 Worked perfectly in a 1971 K5, 4WD, floor shift manual. Did not need to modify the clutch linkage but my return spring rubbed a bit on one header tube so I used and throttle return spring and a hose clamp to shorten the spring route.

    Rated 5 out of 5 by from Great product! I replaced the stock exhaust manifolds on my '83 K5 Blazer. Easy to install, look and sound great. Great fit.

    Rated 5 out of 5 by from Badass headers Put these long tube hookers on my small block 350 and noticed a decent increase in power. Went from original exhaust to open headers and they sure make a difference. Hoping to get some mufflers soon though

    Rated 5 out of 5 by from Great product I'm happy with this product. I bought a month ago.
    Date published: 2016-08-25
    Rated 5 out of 5 by from Excellent product This product bolted right up and increased my horse power right away, no trimming or modifying brackets.
    Date published: 2015-02-15
    Rated 4 out of 5 by from Good quality and fit. I bought this for my 1987 K5 Blazer with a six inch lift. It's difficult to find a pair of headers that will clear the shackle hanger. These fit perfectly. The only modification needed was minimal grinding on the driver side motor mount to prevent possible contact.

    Will these fit a 1983 Chevy S10 with a 350

    Asked by: Venomx45
    No, depending on whether this is a 2wd or 4wd you will need these headers; 2wd - https://www.jegs.com/i/Hooker-Headers/520/2837/10002/-1
