You shouldn't need to retap for the heater hose. There should be a tapped hole on the drivers side of the thermostat water neck for the heater hose. The passenger side is for the temperature sensor.

There are three tapped holes on the front of the intake. Two on the PS and one on the DS. You can utilize any of them you want for your specific application. I put a pipe plug in the DS one and used the two on the PS. One is a small hole for the factory temp sender. The other is larger. I used that for the heater hose.
