    Rated 5 out of 5 by from Do It Very easy to install 92 C1500 with 5.3LS 2wd passenger side required a small amount of massaging on body heat shield and at upper control arm mount to one tube on header nothing major the driver side went on no issue with stock gear shift linkage

    Rated 5 out of 5 by from Perfect fit for LS swapped 1997 C1500 I bought these headers for a ls swap build on a 1997 C1500 Silverado and worked great. Since I am running a 4l80e transmission on my build, the right side ear of the bell housing had to be shaved a bit. Other than that, everything went smooth. The don't sit or hit the frame on both sides of engine.

    Rated 5 out of 5 by from Fit 94 c1500 perfect These headers fit 94 c1500 great. The right header has great starter clearance and the left clears the stock shift linkage. The headers do not hang below the frame. The spark plugs are easy to get to and the wires clear good. The only cons I see is I don’t like Allen header bolts and there is no flange to bolt exhaust to.

    Rated 5 out of 5 by from Absolutely perfect fit Firstly, everyone complaining about the paint being damaged upon arrival, it states in plain ink on Schoenfeld's website that THE PAINT IS TEMPORARY for shipping protection only! Now that that's out of the way, I installed these on my '90 C1500 with a 6.0 swap, and they fit absolutely perfect. Plenty of clearance for the shift linkage and O2 sensors on both sides (square body 73-87 trucks may have tighter clearances). Quick tip - remove your coil packs on the driver's side when installing these to avoid damage to the rear coil. Passenger side slips right up through the bottom, so get a jack and jackstands! Awesome product.

    Rated 4 out of 5 by from Ls Swap Headers they alright, need to wrap them better because they come all scratched up
    Date published: 2022-07-06
    Rated 4 out of 5 by from Ls swap works great I bought these to put into a 77 chevy k10 with a 5.3 all the specific fit headers were ridiculously expensive. These fit nice. As everyone says, both O2 sensors are facing the shackles, but easy enough fix. Works great. Would recommend to anyone with a square body chevy ls swap.
