LS Manifold Replacement for Chevy LS1 LS2 LS3 4.8L 5.3L 6.0L

these headers made installing the ls engine a snap. we went from needing to modify the frame to simply bolting them on and installing the exhaust.

They fit as they should. They do have some casting marks that look like they tried to clean up, so you will see almost polished looking spots on it. I'm probably going to remove and high temp paint them or wrap them before putting into my vehicle.

Used on 5.3 in square body more than enough room !

Let's start with the positives, its a complete set, they do fit pretty well, collector flanges are decent, and it was delivered really quick.Now the negatives...(these are strictly my opinions). The gaskets to head are cheap. I didn't use, I reused the factory metal gaskets. The supplied bolts for bolting to head are cheap, smaller than factory head. I didn't use them I used factory replacement bolts. The collector flanges use what looks like a high temp silicone o-ring to seal. (So far) they are working but longevity is doubtful. They have a grove in them for the o-ring to sit, so using a factory system metal gasket isn't possible.Overall the manifolds themselves seem to be pretty good. The upgrades I did was strictly my opinion on how to make the kit better. You may have good luck using the supplied materials. I however, only wanted to do the job one time.

The finish look remarkable, the paint was nice. Waiting to get the engine to get the fit quality. The price was cheap hope they last like the energizer bunny.

Exactly what I needed. The bags to hold the hardware are subpar though causing one stud and two bolts to apparently fall out. I contacted Amazon customer service and they said I can return the whole thing but all I need is the hardware. If someone could contact me from the supplier and send me the missing hardware that would be amazing and I'd give it 5 stars
