yes, nominally. with low level fittings it is not unusual to find a difference between nominal and actual. when fitting new cups into the head tube it is preferable to press them in rather than bang them in. if that one race is a bit loose you can shim it with a bit of aluminum beverage can material. if you run into a case where the fork crown race is very slightly loose you can make some dimples in the face of the seat all the the way round with a pointed punch. this will effectively increase its o.d. slightly. a scrap piece of metal pipe with an i.d. in the vicinity of 28mm makes a good installation tool for the fork crown race.

btw -

forgot to ask about your Sears bike. at last report you were waiting for a part to come in, iirc.

is she now fully on the road?

you certainly did an OUTSTANDING job both on the restoration and on the documentation.

have very much enjoyed following the course of the process.
