We estimate the contributions of higher K-resonances to the radiative rare decays b -> s gamma. We use the spin symmetry for heavy quarks to reduce the number of independent form factors to four Isgur-Wise functions, which are estimated from the wave function model of Isgur, Scora, Grinstein, and Wise. Our results suggest a substantially larger branching fraction for the decay B -> K*2(1430) gamma than previous investigations.
