Exhaust Options

Hi, I have a 67 barracuda that I am in the process of installing a 360 either with a 727 or a 904. I don't have a set of manifolds or headers at the moment and I am wondering what my options are. Are manifolds readily available?? Is there a set of headers "Shorty headers" that fit nice, don't hang to low that I would have to worry about speed bumps or bumps in the road.
Primary purpose of the car is to be driven on the street even 2-300 miles at a time.

Thanks Jim
