i had an FSA IS-2 integrated headset. I also did a lot of investigating to solve a problem, so i understand how confusing all the information is and how not user friendly it is for someone looking at it for the first time. You are right that it is the Cane Creek standard.

It should fit just fine on any fork that is described as designed for integrated. I think this just means that the fork crown is flat.

You might have to replace the fork crown race as this is hammered down into place, so removal seems unlikely without destroying it. You should take it to your LBS. This is one of the things i do not even attempt to do at home because it is better to use the right tool and you'll hardly ever be fitting a new crown race to warrant buying the tool.
