Headers?
Well to be honest unless your doing alot to the engine headers are a waste... They won't handle the heat as good as your manifolds will and they can warp really easy If the flange on them is to thin.. Most of the time that's with a cheap set but even with a $$$$$ set it can happen.. But if you really won't some go to America trucks.com they sell a few brand of headers just for the f 150s... But read up on the pros and cons of them..
