Replacing my Intake Manifold Question

Dan the man said

I've always pulled the lower hose off as it drains the coolant quicker, it won't drain the block entirely but it will bring the coolant level below the water pump ports, true or false?

the only difference pulling the bottom hose makes vs draining at the radiator tap is speed. oh and mess, lol. the end coolant level in the motor will be the same. so fast drain but longer clean up time or slow drain and little to no clean up time. your choice.
