You will not notice any more HP with headers .Might make you feel more fuzzy and warm on the inside . Chance are you will install a new complete exhaust system with louder mufflers and that louder muffler will make you feel like you have more power ,but you really don't . You will feel it in the wallet . Lol !
Better off spending money on some off road tires or some off road lights if you do that with your truck.
Ps Messing with exhaust manifolds can lead to more troubles when you pull those bolts out of aluminum heads .
