Don't *ever* do this - the water will not circulate properly without a
thermostat as there is not enough restriction to ensure that the water
flows through all the cooling passages.
If you want to check this way, gut the valve piece out of your old
thermostat leaving the outer piece with the hole in it in the housing to
provide some restriction. That way water circulation will be acceptable
and you shouldn't get any localised boiling problems in the head
