And according to @Ultimadude Minato must of somehow halved kuruma's biological body and perfectly pieced it back together again "instantly". I am guessing in case of gyuki it has something to do with the seal involved. Gyuki was sharing Bee's body is the best way to put it I guess. Whereas in Naruto's case its always has been about Chakra.(IT would look absurd if Kurama lost portion of his head after being hit by powerful bijudama)
