Here's a step-by-step:
1. Remove bearings and everything you can by hand. You should be left with two black cup things in the head tube (they have holes in them) and a race on the fork.
2. Remove the cups from the head tube. I very carefully used a hammer and screwdriver. I know it's scary, but my standard cup pusher wouldn't work because of the way Specialized forms the headtube. The cups pop out without too much work, but if you're worried about the caveman method, take the frame to a Specialized shop and they can remove them. After the cups are out, the head tube looks like any other integrated head tube.
3. Purchase Cane Creek IS-2 headset (the other cane creek headsets will work fine, I just happened to use the IS-2).
4. Install new race on fork (the old might work, I don't know.).
5. Push bearings into head tube by hand.
6. The Specialized headset was a bit taller on top than the Cane Creek, so I had to use a 3mm spacer above the bearing, but below the top cap. The 3mm is just a regular head tube space that normally goes above the headset.
7. Your done. I've got thousands of miles on my Cane Creek headset in my Roubaix with no issues.
Replacing this headset is no different than any other headset replacement job with the exception of step 6. Good luck.
