I have a couple of sets of 6.2 HUMVEE exhaust manifolds, they are welded steel tube but not turbo manifolds, you might be able to modify them to fit. I am in the process of building a 6.5 due to the inherent cracked block syndrome. I'm using a 6.2 block and all the externals of my 6.5 so I have spare parts if you need them.
