    1302LS1 is rated 3.3 out of 5 by 21.
    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

    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.

    Rated 4 out of 5 by from The headers work great but I ordered polished stainless and received painted headers not the look I was going for

    Rated 4 out of 5 by from Some fabrication maybe required I bought these headers for a LQ9/4l85 thats in a 1973 crewcab C/K 20 ( 4x4 conversion ) . Both driver and pass frame needed to he ground down to fit . The biggest issue with the fitment of these headers was due to transmission linkage i used .

    Rated 4 out of 5 by from 82 Chevy Truck Installed easily and fit perfectly....except O2 fitting not positioned in a good location so I welded the holes and installed my own. Driver side is close to shift linkage but still cleared. I connected headers to pipe with 3" v band clamps. The shipping coating will need to be stripped so that you can apply high heat paint or wrap.

    These headers will fit the engine, but you will need to check the chassis clearance.
