Before you spend any money on unnecessary repairs get it diagnosed properly. As Timbar suggested a TK test is a good place to start as this checks for exhaust gasses in the cooling system.
How long since the cooling system recieved any attention? The radiator could have an internal or external blockage, the thermostat may be faulty etc etc.

What does TK stand for? Is it worth doing a pressure test?

hows this issue going

Gday to all
well the latest so far with this problem is....where to start, here goes. we replaced the water pump a little while back, had the radiator flushed & repaired, new thermostat. we just replaced the head with a new one the other day as the old one had corroded out into the number 6 cylinder & was pressurizing the system. great i thought..problem solved! NOT!!! now its not overheating as such but it is running at about 3/4 on the temp gauge up to just bellow hot when going up any sort of hill. so back to the mechanic i went. after a while with us all standing around scratching our heads it was decided that i should head to the local radiator store for them to have a look. so another half hour of guys standing around the GQ trying to work it out as even with it sitting in the sun ( on a 33 deg day) at idle for 1/2 hour it stayed at about 3/4on the gauge. so they THINK that i may have a dicky temp gauge or incorrect sender unit fitted ( which wouldn't surprise me as i have only had it about 9 months & have been fixing bodgey jobs on it since i got it), so the next step is to have the gauge & sender unit checked by the local gauge specialist & apparently they can recalibrate it(?). so the saga continues..
thanks to all for the suggestions from everyone they have been a help

cheers

oh yeah i forgot to add that its not loosing any coolant or even appears to be bubbling away,
cheers
