I don't see how any state inspection would spot a leaking heater core,

there would be no leaking. The state was MA, why don't you google for
what they check at inspection?

MA does not care if your heater core leaks or if you **** on the seat.

If the car uses blend doors (most likely these days) then coolant would flow
all the time.

If the heater core fogs the window it MIGHT fail inspection. It could be an
expensive fix...
a stop-leak cube is usually a CHEAP fix - it MIGHT not be permanent
but it will get you through inspection.

The question is whether it gets you through the winter.

Two possibilities:
It will give way and leak many times the original
It will block the core passages so you get no heat on the coldest day of
the year.
