Perhaps they have a borescope or other way to confirm it just isn't a bunch of carbon preventing a valve from closing completely? That seems like the best news you could get. Everything else is some kind of bad-horrible situation.
good luck

Only thing inside the heads is the camshaft and valvetrain. Along with water jackets and oil passages.
Do you know what cylinder is gone(although it may not matter)? Or rather a power balance test? Also did they do a a leak down test? Because it is possible to have poor compression and good leakage readings.
If it's only compression it is probably worn lifters or cam lobes, maybe springs, on that cylinder.
It's probably not both, but if it is it could maybe be the rings or the piston or cylinder itself.
Whatever it is good luck and keep us posted.
