Don't do it. If you had a heater core and the heater were turned off, then the
heater
valve would be closed. So, no heater, block off both heater hose connections.
Or
install a heater valve and close it.

Hmm... let's see... here's the normal path for coolant: the water pump draws
coolant from the radiator and pumps it into the block. The coolant travels
first
through the block, then through the heads, then into the intake manifold, then
back
to the radiator.
So if you connect the heater outlet to the heater inlet in the manner you
describe,
then all you are doing is wasting some of your water pump capacity to move
coolant
from the radiator back to the radiator. That portion of the coolant never goes
through
the block and heads to cool them, so the engine gets no benefit from it.

Those are my thoughts...
