 Good luck with that!  One of the things I found out with my first coffee porter is that coffee has a detrimental impact on head retention--I think it's something about the oils.  If you're bottling, you might want to prime with a bit extra sugar.  Mine took about 6 months longer to mature as well, but once it did--

  I used Starbucks Sulawesi.  Great stuff--in fact, I still have a few bottles from my very first batch of it... more than 12 years old!
