Hemi in a 67 Dart questions

I have been collecting parts to build a 472 hemi for my 67 Dart. I have not seen any pictures of what an A body with a hemi looks like from the bottom. I am interested in what header clearance, suspension and steering mods will I need to do. I think Headman and Hooker both make diffrent size headers but am not sure what to use. Compression should be 10.5 with Mopar alum heads, what would be a good cam to use? I would like the car lower than stock in ride height and was thinking about mini tubs and ladder or 4 bar rear. I plan on mostly street but some strip use.
Any suggestion here or pictures would be great.
