The 1974 350 V8 takes 18 US quarts if you can get all of the old out (e.g. pulling out block frost plugs). I have done the heater core and lost about 4 quarts, perhaps less, with careful clamping of the 5/8" and 3/4" heater hoses.
If you wish to do things without a lot of work, just run a hose from the waterpump spout to the spout on the intake manifold. Before I did the real job, I drove like this for about three weeks.

I also have a 74. Isn't there an inline valve in your heater supply hose? I think most did or had them added. If so, shut the valve off. This will prevent engine coolant from entering heater core. If your in a pinch, take a pair of vise grips and pinch the inlet heater hose off until you can get it repaired..

The coolant in you passenger foot well is unrelated to the cylinder head problem.
Do you have proper tools like wrenches, sockets, a torque wrench, jack, jack stands, etc?

Snapping off an exhaust manifold bolt is not one of my favourite projects! That is normally followed by snapping off exhaust pipe studs. I would make a list of your needs and get an estimate from a pro. Watching them get the studs to the right shade of red before pulling them out is a treat to watch.

I think we're narrowing it down to (exhaust) manifold(s) and possibly heater core leaking on floorboard or leaking at firewall heater core inlet/outlet??????

Are you sure???
You need to disconnect and seal BOTH hoses.
