Drilling a hole in a part is not a fix. The thermostat was defective or installed upside down. But if you’re happy with this fix, all is well.

You may have a leaking head gasket. When combustion gases get trapped behind the thermostat during warm up it delays the opening of the thermostat, it must be submerged in coolant to open promptly. Drilling a hold in the thermostat allows the combustion gases to flow past the thermostat keeping it in contact with the hot coolant.
