IMHO, $700 is pretty excessive. My local dealer wanted less than that for a
HC replacement. I found a shop that would have done it for around $400 but
ended up doing it myself for $65, ~7 hours, and a chunk of meat off of the
back of my hand.
Having seen the HVAC "box" on the firewall, the only way you'd ever hope to
get water pouring out of the drain would be with a failed HC. I guess it
could work its way down from the fresh air intake in the cowl but I suspect
this is very unlikely as it had been raining for a few days and all was dry
inside my HVAC box when I removed it.

Yikes. My first thought would be to immediately return the vehicle to the
shop that did the work and have them sort out the problem that's appeared
since they R&R'd your engine. It could be pinging or injector noise though.
My injectors make a fair amount of noise (always have since new) and can at
times sound like valvetrain noise or pinging.

In my experience, any sort of cooling system leak is something that will only
get worse with time. If your HC is legitimately bad, you should be getting a
coolant smell through the vents.
