Sheer Heart Attack is triggered by heat, and Dio is undead, he shouldn't have any body heat left unless he intentionally heat himself up, despite it having virtually no weaknesses(which is not true... Echoes Act 3 proved as much), Jotaro was still able to put a lot of damage on it, and the damage shows, Dio would have all the time in the world(pun not intended) to crush that little overpowered heat seeking tank to dust, either way, SHA should be useless against Dio.

Bites The Dust only works if there is a living non-Stand user nearby to be its host, it isn't an ability he could simply use at will, plus even if he triggers BTD, he would be without his Stand until he calls Killer Queen back, which completelly disables BTD, BTD is a more strategic ability than a straight up offensive one.

Kira's best bet against Dio would be to vaporize Dio  without causing splash damage, and try to transfer it to Dio through an inconspicuous object like a rock or a coin, but if we assume a situation where both are aware of the other's powers(for sake of fairness), Kira can't hope to win, it would be Jotaro vs. Kira(both encounters) all over again, except Dio wouldn't pull any punches.

Also important detail about Kira's primary bomb, which is also a major limitation: He can only activate it if he touches the object with his right hand, which is also his trigger hand, he can't just activate it if someone punches him on the face despite it still being direct contact.
