They fit my solid axle swapped 1989 k1500 perfectly. Had to cut the right side ear off of the th400. Worked great with the amazon motor mounts as well.

Great headers, fit my ls swapped squarebody with 4l80e like a glove,clears the shift linkage and crossmember. O2 Sensors dont hit anything. Had to trim the passenger side ear of the 4l80e but thats needed for almost every header. Welds look fine too, but i ditched the cheap header gaskets that come with them and used some felpro ones. Does not include bolts, you will need to reuse your old ones.

headers were a tight fit but with mild trimming of the drivers side lower control arm mount and a 2 inch set back from the motor mounts the fitment was tight but sounded and performed excellent on my 89 Silverado short bed 2WD.

Even though the decision doesn’t say they fit 4x4 Squarebody trucks, they do!! Have plenty of clearance for the shackles and the collectors land in a nice spot for the cross member. Had to trim off the passenger side trans ear, but easily done. Nice welds and nice finish. Buy these for your K10, K20 or K30, THEY WORK!!!

The media could not be loaded. I have a 1987 Suburban V20. 4wd with a 5.3 swap and th400 transmission. These manifolds bolted right up. No clearance issues. My motor mounts are lifted about 1/8 of an inch to clear my oil pan. Even without raising the motor these will fit just fine. No problems installing o2 sensors either. Collector o.d. Measures just over 3 inches.

Installed these headers on the L33 Vortec power plant in my 1979 El Camino; 4X4. Its chassis came from a 1972 K20 and the front motor cross member has been replaced with a Pacific Coast LSX unit. I also have a 4L60 transmission. So yes… the headers fit. There were several outstanding unaddressed issues though. 1. The O2 Sensor bungs point directly at the transmission. Had to plug and relocate both. Had to make a 36” extension wire harness for the passenger side. 2. Had to modify the 4L60 shifter linkage be cause it was too close; see pic. 3. Oil pressure sending unit was too close to a header tube; wrapped the sensor; see pic. 4. Header stud bolts were pointless. I couldn’t navigate the headers past them. So what’s the point and all the hoopla. I cut 3/16 of threading off the OEM exhaust manifold bolts and stopped the “bottoming out” issue. The header gaskets weren’t designed for hanging in place either. I had a great fight with the passenger side. Very tight fit. 5. Rather than reversing the shackle bolts that create an interference issue, I cut the protruding threads off. Nuts are self-locking anyway. 6. The 90 degree cutoff / grinder wheel is your best friend. I DID find it necessary to shave a little off the left upper frame rail due to two tubes in intimate contact with it; 1/8”
