Question about 2004 Pontiac Montana
Don't know where to start to find the problem or what to replace.
Sounds like the heater coil is going bad. Do you have water leaking into the passenger side floor? If so, then its definitely the heater coil. Depending on the year, make & model check your fuse panel.

The only sure fire way to tell if the head gasket is gone is to do a compression test. If you are not familiar with how to do a compression test it would be best to have a friend that does know how to do so or take it to a professional.
From your descriptions, it seems likely that could be the issue as if the head gasket goes, you will run hot if not overheat and it will be difficult for the engine to run and when it does there most definitely be smoke out the exhaust.

When u put the heater core back either you mixed up the A/c controls with the heater control, or the gate that allows air across you heat ex. is not opening.
Feel the temperature of the water going in and out of the heat ex. (open the hood and feel down by the firewall where the pipes go thru)
If it isnt hot going in there is a valve problem not allowing water to circulate.
If both are hot, then the blower gate isnt opening or the A/c control is confused with the heater control. ( a bit unlikely)
Hope that helps

remove coolant.remove thermostat remove bottom radiator hose to water pump.put a empty container under the radiator.take a water hose put it where thermostat goes flush out the rust in block.watch the water as it come out the water pump .if stream water is small keep flushing until you get a study sream of clear water. also flush out radiator. lower water pressure dont flush radiator it with high water pressure you could burst it. make clean the over flow jug .make sure it not stopped up.put in a new thermostat and radiator pressure cap. fill radiator with half antifreeze and half water.bleed the coolant system.

Had the same problem and turned out to be that the Heater Core was clogged. Took it to a Radiator shop and they blew the system out to unclog it. Cost was $25.00. 2005 Grand Prix.

Air in system, bleed system manually by filling up reserviour then drive until operating temp. Leave vehicle to cool 2hours or so then refill again. repeat until heat is steady and guage stays normal
