Ok, essentially you want as low a stack height as possible without the crown hitting the frame. Im running a pair of teams on my norco. It has a ht of just over 5inches and a stack height (including the headset cups) of just under an inch and a half. I use a drop crown and it claps on pretty much so all you can see at the top of the stanchion is the chamfer. If i was to really stack it hard and compress the bumper the crown *may* hit the frame....but id be more worried about me after one that hard.
From the sounds of it, you would need the drop crown and be running about the same stack height as me with a head tube as long as yours. Although headset does come into play, the blackspire i have on the norco has a lower cup height than the hope that i had on the stinky, soo, this means that the lower crown was pushed down further on the stinky than it is now which also affects all the lengths. The best way to find out is to pull the stem and top crown off, and play around with a few spacers in there and hope you still have enough steerer tube length left.
