    2451-1 - Hooker Headers Competition Headers Chevy/GM Car is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Good Fit Bought these to replace a older set of painted Hookers. The new ones fit very well. The LH collector bolted up to the existing reducer perfectly. The RH side was a tad higher, closer to the crossmember. Had to cut and reweld the RH reducer to get a good bind free fit. Overall very pleased. The finish is good, some imperfections. The only negative note is on how they Dented the #1 tube for #3 plug clearance. Rather large and amateur looking. Could have been a lot smaller. Overall, thanks hooker Good Job.

    will these work on 5.7 350 vortec motor going in a 84 chevy c10

    Asked by: bud 1
    No, these headers won't fit your 350 engine. You will need a header like this - https://www.jegs.com/i/Hooker-Headers/520/2453/10002/-1
