I don't think anybody local has the equipment to do the high temp coatings you are probably looking for.

Stock or after market?

I think the consensus is it is a good idea for the thinner tubing based after market ones, but the stock cast ones really don't need it. Now an extrude hone and port match on the stockers may be a good choice if you really have spare money lying around.

Doing anything with the headers is usually one of the last mods before you start spending money on engine internals etc... as they have a very low HP/$ ratio.

Typical power mods from the engine back is more or less:

Access Port
Turbo Back exhaust
Up-pipe
Turbo
Headers
Engine/head work
