Higher flow will increase heat transfer.
Not exactly.Not true on 87 and up TBI engines, The intake gasket has a restriction built in to it at the rear coolant port on each side. It is there to slow down the flow of coolant to allow the coolant to absorb more heat from the block. GM put a TSB out when these trucks first hit the market because service techs were installing the old style gaskets on the TBI engines causing over heating problems.

The gasket is not restricted to protect the heater core. The gasket is restricted to assure that heated coolant is circulated through the passage in the TBI intake manifold, to promote an even, warm intake manifold temperature.
