Nice "unmod". I'm a firm believer in stock exhaust manifolds for a variety of reasons looks, ease of plug access, less heat in the truck, easier on the starter, etc. With the center dump ram horns, the wires were designed to run underneath along the block and up to the plugs with 90 degree angle boots. Cylinders 1,3 and 2,4 actually come up through in-between the block and motor mount. Run like that with the stock heat shields, they shouldn't burn. One other note, if you are keeping your truck stock, I don't believe that the heat stove sheet metal will fit over the 2 1/2 " exhaust manifolds - you would have to stick with the 2".
