You can see the lift points on the weld bead. It was positioned 3 times during welding. Here we'd throw it on a turntable but that one appears to have been done by hand. nice work either way. My experience with Chinese stuff and Ive bought a lot of industrial welded material over the years directly from China is that they will build according to whatever spec and payment base they are sent. You pay for crap , you get crap. You pay for quality you get quality. These headers appear to be quality so I wonder what the basis of the original contract was. Ive got a "Manley" Chinese made crank in my 540. I dont believe for a second that Manley did anything other than put their name on it. I still trust it to 1200 HP. Same with the Scat rods , the "Weiand" intake and I even suspect the pistons were Chinese sourced by Mahle. Not losing any sleep over it.
