Another thing we are not putting in the equation, is the water hole configuration on the head. Those huge centerline trapezoidal holes in the block do not determine much, as the head and gasket holes open or shut the gates anyway. The worst consequence of those 3 large centerline trapezoidal holes is the corosion damage they do to the heads as they meter the flow with smaller holes.

I agree with B&S on the issue I was presenting with my early concern about using the round hole gaskets and water leaks. Using what you find when inspecting gaskets for how they match the block, you will find, the gasket designs do not reflect any need for water holes copper rings, need for a crush upon installation. Frequently we find copper ringed holes without crush as a design rule.

As to water flow and how much heat it carries, that is an age old argument we need not try to settle here.
The answer to my original question then is basically, - they both would be fine.
