What are the consquences (especially doing more damage or safety
hazard) of driving with a cracked manifold (something in or near the
exhaust system)? I've seen some other posts about how to temp fix,
replace and where to take if needed. but what if I just keep driving
it. One place missed it, 2 others confirmed it was there.

If you run it hard and put it away cold, you'll warp an exhaust valve
for sure.
$134 will buy a new manifold:

Of course change the search criteria to fit yours.

You have a CO risk. Basically if you open a window, you need to open
one on the other side also to avoid a vacuum into the cab area which
will suck it in.

Watch for a tight feeling in the forehead with a headache or an
uncontrollable sleepy/heavy eyes feeling. If you get either, get air fast!

Also watch the wiring so any hot gas jets out of the leak don't hit them
melting things.
