As has been said, you'll need at least 70mm more than the length of your head tube. It isn't clear what size your frame is though. You say C-T of 19 which suggests size 19 and 130mm head tube. But the C-C of 17 suggests size 20 and 150mm head tube?
You should find plenty of forks with 200+ if that's what you need, as they'll have been cut for size large frames which are quite plentiful. But 220+ would be a bit more difficult as there are fewer XL frames around.
I could sell you a Z2 with a 213mm steerer if that would suit?
