the bolts your speaking of dont have a "head" Its basically a two sided bolt you could call it. There are two sides of threads separated by a little gap of just metal. Half of the bolt screws into the manifold up to the thread separation (the metal gap) Then you would have the other half sticking out, which it what the DP slides over, and then is held on by nuts.
When you pull them off to change you flexpipe or whatnot the nut itself may come off, or the whole bolt may come out. It depends on how much corrosion is holding the nut on to the thread.
You defiantly dont want to break those bolts trying to get the DP off. Use heat if necessary, alot of penetrating oil wont hurt. When i work on something with alot of corrosion like that i back the nut or bolt out a couple turns, then thread it back in a little. It cleans out the threads of crap that may be binding up. It takes a little more time but its worth it.
BTW, you can get a replacement flexpipe for it for autozone or oriellys. Mine was 25 bucks, beets the price of a new DP. Their sitting on the shelf with all the exhaust pipe. Just cut the old one out and weld the new one in. Just make sure the overall length winds up the same.
