had radiator flush, thermostat install, and was told head gaskets are fine, still over heats sometime, and heat in the car doesnt wrk all the time. when car is overheating no heat in car when wrkng properly heat in car is fine, running out of options. car has 214,000 mi but is in good condition. any other ideas what it could be.....could it be the water pump, or does it has to be the head gaskets?

214,000 mi. ? Yikes That puppy's tired, sounds like the water pump, or radiator, or bad heater core.

check your fan clutch. If its going bad it causes your fan to no turn fast enough to cool the engine.

It might be:
The water pump, thermostat, radiator, out of coolant, out of oil, fan isn't working, or the dreaded head-gasket. It can be a lot of things.

The problem is with the water pump have a full inspection in that area.You will get the solution.
