The V10 2 valve engine has very poor exhaust manifolds. The 3 valve engine has very good exhaust manifolds, and flow pretty good. To notice any improvement in performance a very good set of exhaust headers is needed for the 3 valve. Any set of headers will show improvements in performance, heat reduction, and some mileage, for the 2 valve, depending if you can keep your foot out of it. Haven't herd of very many problems with the 3 valve exhausts, but it can happen. If the bolts keep loosening, the heads may have had the threads stripped, or pulled, and need a repair.
