Old Hiruzen died to Oro who didnt even fight him with his own hands, Orochimaru arguably stronger in Shippuden, lost to Vers2 transformed Kyuubi Chakra Cloak Naruto, so with Kyuubi, pretty safe to say Naruto wins.

No Kyuubi? Im not sure if Hiruzen has his whole arsenal of jutsu like he did in the war, but if his old age causes him to have difficulty in using his jutsus, then Naruto could easily enter Sage Mode and overpower Hiruzen.

If Hiruzen however has his hige arsenal of jutsis, then there may be a small chance he wouldn't allow Naruto to enter Sage Mode and base Naruto is still pretty weak here, no? With these conditions, I'd say even then, its a 50-50 chance, though I might be ignorant of some facts
