Blocking water pump to heater core

Can you block the out from the pump and rear of the intake or just run a hose between them ? Going to start a engine on a run stand Car probably won't have a heater also.

Factory heater delete cars simply blocked the ports. There is no need to run a hose. Consider that there is no hose going to the rear driver side anyway, so what makes the passenger side different?

For a quick job you can just throw rubber caps on them. Every rubber cap I've used in the past few years has failed within a few months, so keep an eye on them.
Next time you have the water pump off the nipple can be tapped for a plug and you can replace the heater control valve with a plug.
