I apologise if you are already aware of these references. 1 The first reference attempts to solve this problem but only gives a partial answer. The second reference shows that every 3-manifold can be obtained by surgery on a link (but does not discuss Kirby calculus). MR1075370 (91k:57019) Rêgo, Eduardo ; de Sá, Eugénia César .
