Both heads will be ok. Carefully look at the intake and exhaust valve seat match to the port bowls for any excessive core shift. If your finger nail catches under the bottom edge of the intake seat, pass on those heads..........I have found the that GENERALLY speaking the 862's are a better casting than the 706's.
Good luck,
