Would you think its a Thermostat that is acting up? (We let all the air out of the coolant system). Is there anything else that can cause overheating?
Thanks for advise.

The head been resurfaced by a profesional shop. Looks like the head will come off next week to get inspected for cracks.
1,2,3 cylinder get water in if you pressurise cooling system. If you you do cylinder pressure test it wont blow coolant out, so it does not appear to be bad gasket especially that its the same exact problem as before the head was resurfaced. It hasnt been the gasket in the first place as it still takes qt of coolant for 10-15 miles. It does not mix with oil. So far diagnosis been that one of the coolant passages might have been damaged before or during porting process as I got someone elses head from Buschur based on the core exchange basis.
So. It sux. I am into it for about $1000 now and still not resolution as of yet.

Oh man that is sad.
Did you contact the vendor? , at least they should replace the head. and they should have a record on whos head is whos. Also you could recover some of the money selling the replacement head.
