Get an aftermarket 2 piece manifold. Cut the top and bottom bolt holes open so that you can bolt it onto the wider bolt spacing of the IH engine. Then drive the manifold apart about .125" at the seam. Use a punch to indicate the centerline of the ports at the front and rear of the head and on the outside of the number 1 and 6 exhaust manifold runners. Align the punch marks when you torque it down to assure proper port to manifold alignment. Done in 20 minutes. A biscuit Cutting wheel on an air grinder makes very short work of the process. Also aftermarket manifolds allow for different turbo bases. A simple riser is needed to set the turbo higher if going in under triple 6 tin. Turbo will sit up above number 2 cylinder and look like it was meant to be there.
