I remember reading that J-heads are drilled slightly below the nominal diameter, to allow for wear in time. Your experience seems consistent with a slightly under-drilled J-Head (say 0.32 mm), with the free-air spaghetti always being quite a bit larger than than the bore (say 0.38 mm), and with the need to stretch it just a little for the bridges (back to 0.35 mm). Please note, I pulled those numbers out my body part closest to the chair.
