You can do it either way
* Route heater tap on cylinder head back to heater pipe (just without heater). As you note, this is how it works from the factory when the heater is open (lever fully to HOT), back of cylinder head is connected to radiator pipe
or
* Block the tap on back of head. This is what Datsun did for STD 1200s without the optional heater
Nissan part number 00931-30610 PLUG-HEATER OUTLET HOLE
Heater hose plug for cylinder head (as fitted to no-heater models)
Plug thread is 3/8" BSPT
