a little headset help here?jw25

I just found a NOS TangeTechno-Glide sealed bearing headset. Problem is, the cups seem undersized for my frame. The old (Stronglight) cups were in snug, and were removed with the proper Park tool. The new Tange cups didn't quite slide in, but after pressing them in, I could rotate the lower cup by hand.
Any recommendations? I know green Loc-tite can fill gaps, and is made for interference fits. I don't know if there's enough space here, though. I suppose I could run the old HS again, but I've hard a hard time keeping it running smooth (needle bearings).
Thanks

The cups might be JIS standard, instead of ISO (30.0mm instead of 30.2mm). I'll pop the cups out and see if I can mike them. I'd still appreciate feedback on the Loc-Tite idea - it's a nice smooth headset, and I'd like to use it if I can.

Loctite should work fine - once the headset is installed, unless the bearings are trashed, the torsional loads on the cups are actually pretty low - they won't spin in the frame (just make sure the head tube is faced properly!)
