your missing a lot of info headers are short or long? what cam/tuning? throttle body is electric not sure where your going with that and the heads rarely need modifications unless under boost.

mopar intake , kooks long tube headers and high flow cats.. stage 2 hhp cam with new valve springs and retainters and electric throttle body

for the money long tube headers are not worth it SRT challengers already have short tube headers and the extension of the headers with highflow cats will set a CEL. The throttle body is also kind of pointless unless your going to upgrade the whole intake manifold. And I would not touch the heads unless you are installing a supercharger the CAI helps a little and a cam might give you 40 hp so your going to be spending $1500 on tuning for that cam and to reprogram the pcm so it will recognize the new locations of the o2 sensors. and if you do the heads that's probably $3,000 worth of labor and machining for not much gain. instead you might want to just look towards a supercharger kit for 4k and for a little more coin you can get a whole lot more power.
