What do you guys think?

Lately I have been looking for some slant 6 parts to spruce it up. I picked up a 4 barrel intake a few weeks back and now looking for some headers and carb and a cam. I came across this craigslist ad and to me looks like a good deal. I am just looking for some guidance. Thanks for looking. I am doing this for a Challenger. Will the headers fit my car?
