Ok, I am getting fed up with my car.
My temp gauge doesn't work.
I replaced both the one next to the water pump and the one in the head with sensors from advance auto parts.
No change.
I then replaced the one in my head with an ACDelco from a GM dealership.
Now instead of the needle just staying at the very bottom, (below the 160 mark) sometimes it would move up and stay exactly at the 160 mark for a little while then drop back down to the very bottom.

I do not know if this helps but:
I am not running much antifreeze cause every time I change a sensor I loose a lot and then just fill it out with just water.
It doesn't get that cold at all where I live. (SC)
Also the day my gauge went out, I installed white gauge faces and removed the needles during the install. Is it possible that it is just not calibrated?

Car is a 1996 Camaro LT1 OBD2
Please if anyone can help me out, I would really appreciate it.

I think thats your problem right there. I think you pull the needle off and didn't put it back in the right place.

Bring the engine up to operating temperature with gauge bezel removed. Pull the needle and put it where it used to sit at normal temp - usually just left of the center mark. Let it cool down and see how it works, assuming it's ok, put the bezel back on and button up the lower dash.

that or your needle is sticking to the backing.

How can I tell where the right spot for it should be?
Is there a correct way to put the needle back in side then move the needle to where it should be?

I need to correct myself, I changed the gauge faces after my needle stopped working.

If your gauge was wrong due to a bad sender and you put the needle back in the wrong place you could have this problem. If you have a volt meter you can do some testing but I would remove the gauge bezel like I described above. If the car has a stock thermostat then normal operating temp is about 205, bring it up to temp and put the needle just to the left of the 210 line.
