Default Vortec "880" block for a TBI application

I am wanting to use a Vortec "880" 350 block in a TBI 350 application.

The Vortec block does not have a coolant bypass hole where the water pump bolts on the passenger side.

The TBI 350 block has a hole in this location that mates with the water pump.

How can i use the Vortec block with the factory TBI waterpump,intake,etc?

use the gasket as a template and use a 3/8" drill bit to drill the hole.
but i don't think you really need to worry about it if you run a heater core, since that will function as a full time bypass unless it has a shutoff valve inline like some AC cars do..
