with my gt4 (185) the standard heat shield does make quite a bit of difference. With it on everything is sweet, after i switch the engine off with the heat shield off I can hear coolant boiling in the top tank of the radiator and much more steam seems to escape from the relief hose.
I would chase one up and put it on, in addition you might want to source or make a heat shield for the radiator, if youll notice near the turbo on the radiator there are 2 threads for bolting this shield on, it helps a little aswell...
In addition, maybe you should wrap the dump pipe, that could help a lot....
