Small block header options with O2 bungs?

I need to figure out what headers to run for my Duster project. Originally planned to go with 340 manifolds and have the o2 bungs welded in the lead pipes. Really wanted the manifold set-up to keep from cutting/welding on the console shift linkage. Plus I would like to run a full size starter. However I would like to find something that is polished ceramic coated to give a nice look.

70 Duster
360 mounted on a 73 spool type K-member
727
console shift
power steering

Suggestions?
