If anything, your head gaskets may let go at some point or a head may continue to warp or crack if it were already on the way after this. Either way, you'll definitely know when any of that happens.
You can do compression and leak down tests to make sure everything's in spec now. Monitor for mixing of fluids (oil/coolant) and watch the coolant level for a while. If all that stays normal, I'd just drive it.
