I suspect that it in fact decays via double electron capture directly to 64Ni. If so, you might not get any energy at all, because it would all go with the neutrinos. The first excited state of 64Ni lies at 1346 keV, which exceeds the decay energy (about 1 MeV), so the decay can only occur directly to the ground state, implying no gammas, hence the energy is "gone with the wind".
