If the heater doesn't blow hot then that mean that it's either plugged up with sludge which will also be throughout the cooling system or it has an air pocket because the system is not full of coolant or it has a blow head gasket.

No, you can't do that. All systems build pressure as heated. They have chemical tests for that.

Agree with HT...Also, a gas analyzer can be used to check for HC's present in the cooling system (easier, cheaper test). If you have a $10K analyzer.
