Bought for my 1975 c10 they bolt right up and fit great. One spark plug boot on drivers side 2nd from the front was a little tight but everything else was perfect

The headers appear to be great quality. Welds look great And they even attempted to bring the inside primary welds. Could use a little more bringing but I won't complain. However with my ict conversion mounts to factory mounts they don't fit with ought some cuts to the motor mount extras. But over all for being a swap header it may fit yourmotor location to swap mounts

Fits my 78 c10 chassis perfectly but the 2nd tube back on drivers side is pretty tight to the spark plug but other than that they fit great and weld are very nice and the flanges are nice and thick

Picture doesnt match what was sent to me. The polishing is horrible an just looks like a blind man did it. Plus it showed up all scratched up from there poorly packing. Very disappointed

Description says its fits 1960-1998 2WD Silverado. However it did not fit on my 1989 2WD Silverado. LS swap engine mounts were used and these headers crashed on both sides. Pictures show where they did not fit.

I bought them for a 5.3L LS swap on my 96 OBS truck. I waited too long to install them and can’t send them back. I’m ok with having to make changes with the truck so the headers would fit but I shouldn’t have to modify anything on the engine or the header. The #1 cyl pipe is poorly thought out. It is so close to the #3 spark plug you cannot get the plug wire on the plug without it touching the header. I’ve tried several different types of wires. My only solution is to heat up the pipe and put a large dent in it where the plug wire touches. I don’t recommend this product.
