How do i bypass the heater core 96?

How do i bypass the heater core on 1996 LT4 6spd? i have major leak coming from the heater core/reservoir area inside the engine compartment, not inside the interior (yet).

Would turning the heat to "Off" help (not leak)?

Coolant runs through core full time; turning heat "Off " only changes the airflow through core.
Disconnect both lines in engine bay going into core ( at firewall ) and either join together with a piece of tube or block each one individually
