Thanks for the answers everyone. @ Bob Engle: I checked the engine and the there is no water in the oil and the head gasket is still fine. Also there is no white smoke when the engine runs and all cylinders have full compression (I did a test on it). @AzBob: Thanks for the link, I will try to contact the guys behind restorationstuff.com, I alreadyd contacted Bob @ Bob's Automobilia, he does have some parts I maybe able to use. How much water should actually be in the radiator when the engine is not running? If I do fill it to cover the core, there is not a lot of room left to the top of the radiator, only about 1.5-2 inches...
