We need to know what year your truck is at least. Did it run like this before you put these mods on it? A little more info is always helpful
. I'm going to take a shot in the dark here and say since you replaced manifolds with headers, that somethin is screwed up with the O2 sensor.
Reason I say this is because once the truck warms up to "normal" temp, the computer goes into closed loop, which is when all the sensors kick in and monitor whats going on at various points of your engine. If your O2 sensor is messed up, it will cause a problem.
