You can use Tooltip:


With[{min = -8, max = 8, nbr = 5},
 ContourPlot3D[x^3 + y^2 - z^2,
  {x, -2, 2}, {y, -2, 2}, {z, -2, 2},
  Contours ->
   Range[min, max, (max - min)/(nbr - 1)],
  ContourStyle -> (n = 0; Tooltip[#,
      min + (max - min)/(nbr - 1)*n++] &),
  Mesh -> None]]


contours = {-2 Pi, -3, 0, E, 7};


ContourPlot3D[x^3 + y^2 - z^2,
 {x, -2, 2}, {y, -2, 2}, {z, -2, 2},
 Contours -> N[contours],
 ContourStyle -> (n = 1; Tooltip[#,
     contours[[n++]]] &),
 Mesh -> None]
