Your question is actually a little confusing and it is late...
Headset for your bike will be 1 1/8... if you have the right fork the steerer should be 28.6 or 30.015 mm at the crown race seat and there will be some space between the steerer tube and head tube as this has an ID of almost 34mm.
A 1 inch fork will measure 25.4 and either 26.4 or 27mm at the crown race seat depending on whether it is JIS or ISO.
You can get headset reducers to fit a 1 inch fork in a 1 1/8 frame..
