i believe it is a head gasket or cracked head I have changed thermostat and it continues to push out coolant even before thermostat opens, what I dont know is how to be sure and where to start diagnostics

Well, pressure test the system, because you could have a clogged radiator, lower end, or upper end. So lets not rush to a cracked head or gasket.
