Glad to hear that...in the meantime, I'd be sourcing a new head gasket kit to suit the motor...I wouldn't race out and buy it just yet, just find out where you can get it quickly.
Once you have the motor running (with the heater isolated) if you spot any leaks, shut it down and investigate further.
Also...if the car has been standing for a few days, it might be a wise idea to pop the plugs out and then wind it over and observe what might come out of the plug holes...if coolant is ejected, the head needs to be removed. It will either be a blown head gasket...or a cracked head.
Fingers crossed for you.
