    1302LS1 is rated 3.3 out of 5 by 15.
    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 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.

    Rated 4 out of 5 by from Overall good product I bought these for a swap into a GM square body pick up. They fit pretty well but required slight modification. On the driver side, I had to notch the frame a quarter of an inch, and the 02 bung had to be moved about 20° counterclockwise. On the passenger side clearance was tight on the heat shield on the firewall. Had to massage the heat shield a little for proper clearance. Otherwise, I'm pretty pleased.

    Rated 3 out of 5 by from No gaskets or bolts The reason for 3 stars was it showed gaskets and bolts but didn't come with any.

    Rated 3 out of 5 by from Nice looking I bought these but have not installed them they came on time but like other reviews the black is scratched off in places from shipping but not important

    Rated 3 out of 5 by from Cosmetics, shipping and fit were all wrong. I installed these on my c20. They cleared the slave cylinder on the driver side which is great but the passenger side cam out directly in the middle of the transmission cross member. Had to make a new crossmember to clear it. They put nothing in the box to protect them during shipping so the coating was all scratched up and the flanges bent. They work great now but do not purchase unless you’re ready to do some fab work.

    Will these headers fit an LQ4 from a 2003 Denali?

    Asked by: JMac103
    These headers will fit the engine, but you will need to check the chassis clearance.
