Taking out the thermostat and putting extra fans on is just covering up the problem!
You need to find out why it's overheating and fix that!

Alloy radiator, Radtec intercooler (front mount) and 2 9" fans.What is going to cause it to overheat tho?

Head gasket, air in the system.

Is the system under pressure when the car is hot?

HG, poor mapping, warped head/block, blocked pipes, radiator, or water ways, crap water pump, etc..

Its only just been built so the HG should be ok? Its not run in yet so hasnt been mapped and like I just said its only just been built so all the water ways and stuff should be ok?

Yeah if you undo the cap it releases air?
