Stupid coolant flow question:)
The water pump draws the coolant from the radiator. The coolant is then circulated through the cooling jackets in the following components, then back to the radiator to be cooled:
The cylinder heads
The engine block
The throttle body
The engine coolant is drawn from the water pump and circulated through internal passages in the cylinder heads and engine block. Vapor is vented off through the coolant air bleed pipe. The heated coolant is then directed back to the radiator. A separate coolant flow loop is available from the coolant pump to the heater core and back to the coolant pump to provide passenger compartment heat and defrost.
The radiator surge tank provides a coolant fill point and a central cooling system air bleed location. The tank is translucent on the lower half for coolant level viewing.

the old chevy's water pumps use to suck it from the bottom. but gm stole the reverse flow idea, whole nuther story
lawsuit is still pendingbut now water pump sucks it from the top and it does cool better
but i am no mechanic and i have been wrong before and will be again
google Evans water pump

Check your LT1 history books.....
By the way, the LS1/LS6 engines do not employ reverse cooling.
