Your Spotties are the most likely causeQuote:

TD is probably on the money with a blocked rad internal or external, same result. Hosing through the cores may dislodge any mud caught in the fins, DON'T use a gerni as it folds the fins over.
After an engine build is it possible you have an air lock.
On the 4.2 there are 2 small (10mm diameter?) caps on the bleeds, one at the thermostat housing and one at the rear of the motor.
Take them off one at a time and run the motor for a few seconds to expel all the air.
Easier to do with a mate starting and stopping the engine.
Invert a cut off coke bottle in the radiator opening, park with your nose uphill as well..Keep tipping in water and squashing hose
This way you'll remove all or any air bubbles that may be trapped, good luck let us know how you get on.
seems a shame this happens after all your good engine work
I just hope i have not done any damageQuote:
