Go ahead and port it out. I've ported many an exhaust manifold, and while not quite as good as headers it does make a substantial difference. As for where, any shop that offers head porting should be able to do it (ie any halfway good automotive machine shop), the time involved could be a bit because cast iron takes a bit more effort than aluminum, but with the right tools is not a big deal. As for the coating I like jet hot, but I'm not sure I'd bother with cast iron unless your goal is to make it look nice.
