Those V6 Honda/Acura motors pressurize their heads first, then the crank from the front first, rear last. So the middle of the crank (#3/4) starves oil at the rod bearings. Usually the mains will rattle/hammer but not spin or sustain real damage. The rod bearings usually take the brunt, often spinning or melting/seizing.

If it is running now, it's either knocking (damaged/spun rod bearing, overheated/warped rod end) or rattling (bearing clearances).

I seriously doubt anything in the heads got damaged at all, and the cylinder walls and pistons are probably fine too. The rings may or may not have sustained any real damage.

In most cases a new oil pump, rod/main bearings, and new rings and it will be fine.

Runs but is knocking/ticking. I need to dig up the final diagnostic test performed by Acura. I'm certainly not in a position to rebuild though the thought has crossed my mind. My experience in dropping/rebuilding engines is all VW related. I think this is a little more complicated.
