Question about Cars & Trucks
I would suggest that you replace the thermostat. The thermostat should open to allow coolant to flow thru the engine but if it is stuck closed the engine will continue to heat up. To find the thermostat follow the upper radiator hose from radiator back to the engine and your hand will be right on top of it. Make sure engine is cool then remove the two bolts holding it in place and just lift it out and put in the new. Make note of placement of thermostat this is obvious but some have put in new stat backwards, do not do this. Also, replace caskets which usually come with new thermostat.

Did you replace the thermostat? How long does it take to overheat? Is there water coming out of the tailpipe? Do you have to keep adding water to the radiator?
Sounds like a blown head gasket from the engine miss. Pull the spark plugs, if any of them are kind of a bleached white on the electrode then you've got water in that cylinder and either a blown head gasket, cracked head/block, or a combination of those.

Sounds like there is air in the cooling system causing the engine not to overheat but the heater not to work. Flush cooling system and work the air out of the system.

Firstly, ensure you have the required 'mixture' of coolant/water (must have required coolant).
Second, I would recommend you re-test all the cooling system sensors again (make sure they're within specifications), in case a new one is faulty.
Third, ensure the new thermostat was of the correct temp setting (they all differ), so that it opens at the required time. Most cooling systems operate within 90 - 100degC.
Fourth, make sure the radiator (and associated hoses) aren't blocked.
If your temp gauge is reading higher than normal, but NOT in the danger zone...then this can be considered normal (especially if you've replaced with new components) and nothing to be concerned about.
However, if the temp gauge IS in the danger zone....then this suggests the coolant is not flowing through the cooling system properly.
If all above components test ok, then it's possible your water pump may not be pumping enough volume.

Testimonial: "I appreciate your help...Maybe I should just relace the water pump, that would be the last thing that I would need to replace."
Yes, you can, but not exactly recommended. If you are going to go that deep into it, then might as well do everything else. However, being unemployed tends to have a negative impact on the wallet....
I suspect it is more than just rings. I think that the walls have been scored badly as well. You may be able to use a borescope to take a peak into the cylinder through spark plug hole. Move the piston to bottom of stroke, and see what you can see. If scarred, much work will be needed. If hatches look alright, then you might be able to get away with just rings.
What kind of compression are you getting on #1 vs #2? This also might be a blown headgasket into an oil passage, or the head (perhaps block?) is ever so slightly warped in this area.
