1. Holley Sniper coolant temp sender?

2. Dash gauge coolant temp sender?

3. Heater return line?

BTW, the fitting on the intake manifold is the hot coolant to the heater, and the heater return goes to the water pump.

If you must use a heater hose, this is correct.

Using the return hose would be like placing it in the bottom hose, as the return from the radiator.
