Well as far as any records go, there's no evidence to suggest that any of the B2 fleet was re-engined in such a manner. The documentation I gleaned from Woodford many years ago stated the engine fit when they were delivered and there are no records (at least none that I've ever found) that suggest that any aircraft were subsequently changed.
Incidentally, you can see the afore-mentioned intake differences on a photograph on page 87 of my old
Vulcan Story book if you have it
