Hello all. My DD is has a set of headers on it that are going south.... Looks liek I'll be rigging them for the time being until I can get new ones and new exhaust. I have never been a big header fan due to the problems with leaky gaskets and rusting, but they came on this ride when I bought it... Ok, so do you think I really need them and they make that much of a difference? The truck specs are: 383 - 350 .30 over, Trick Flow twisted Wedge heads, Scat 383 crank, Manley rods(6" I believe), KB Hyperu pistons, Comp cam, very hi compression(pings even when running 94oct without retarding the timing), Holley 670 TBI.... I cant see them making a huge difference on the butt-dyno, or will they? I would liek to go to manifolds so I dont have to worry about'em.... What'cha think?
