No boilover or gurgling on the front could mean that the gauge is out of calibration or wiring problem. No heat -might be a bad thermostat/clogged heater hoses/heater core/heater control valve.

I changed the thermostat also. I changed the radiator cap as well. Do you think it could be the heater censor that controls the temp gauge? If not what else could it be? Also it has alot of pressure when I took the radiator cap off and it was gurgling. We did flush the radiator with the proper stuff it had alot of sluge in it. Could I have a back up somewhere and if so where should I look first?

Try this-Bleed the cooling system see below and report back

Always bleed air from cooling system after replacing coolant. Set heater for maximum heat. Remove radiator cap. Loosen drain plug and remove drain bolt (if equipped) from engine block. Drain coolant reservoir. Fill coolant reservoir to MAX mark with 50/50 water-coolant mixture. Loosen bleed bolt and fill radiator up to base of filler neck. Close bleed bolt when coolant flows out without bubbles. Tighten bleed bolt. With radiator cap removed, start and operate engine to normal operating temperature. Add coolant if necessary and check for leaks.
