Missing the gasket which was annoying. Also it fits a few different models so note the big block off plug doesn't let one one of the tie straps be reinstalled. Aside from all that it was a great product. Bolted right on and works great. Good value for the money.

Great quality, fit perfectly on my 95 k1500 5.7 350 V8, passenger side. Comes with 2 sets of gaskets, make sure you install w/the shiny side out. Torque specs called for 26lbs on center bolts & 20lbs on outer bolts. However, I had to torque all the bolts down to 35lbs to get it to seal properly. Truck runs great now, no more exhaust leak. Very happy with purchase.

These are made in China, but they'll probably be fine. The mating surface to the head is milled flat and the machining at the flange is A-OK. I bought both sides to replace my rusted out manifold studs. Instead of wasting time trying to get rusty nubs out of my OEM manifolds, I made life easier by using these manifolds. These manifolds have the same heat shields mine had.The kit came with the donut, studs, springs, and nuts. For whatever reason my driver side manifold came with the gasket for both heads, but the passenger side manifold came with no gaskets. It worked out for me, but just know that.They come with a plugged port that must be for emissions stuff. I didn't need to use them so I got after the ports with my die grinder to open them up as much as possible for better exhaust flow.That's it. I have no exhaust leaks and they look nearly identical to OEM. We're lucky Dorman makes these as cheap as they are because trying to salvage the OEM ones would have been an exercise in patience and persistance.

This exhaust manifold was a perfect fit on my 90 GMC 2500 with the 350ci engine, although it does not not come with gasket for the engine like the picture shows (at least mine didn't). Very good quality product that looks just like stock. Part showed up at my door before I expected. Very happy!

OEM quality, no install issues. Comes with gaskets and some hardware, wish it came with bolts for the cylinder head, had to run around a bit to find those

Quality product only downside is that it was from China. Bolted right in with no problems. Update the manifold cracked into two pieces so i had to find a used replacement.
