It seems to me the the cost of to shot peen the rods, new bolts, flashing them and the time and effort you can get a new set for cheaper or about the same cost. I ditched my stock rods in favor of some eagle forged h beam rods (with their ESP armor) using the strongest bolt possible. These rods can handle 1500 HP no problem, plus (with my forged aluminum pistons) this thing will zip to 7500 real quick (but I have a rev limited set at 6400).
