528 or 472? Siamese or no?

I've heard Siamese bored big blocks (like the 528) overheat a lot, and the cast iron street blocks (like the 472) don't have as much of an overheating problem.
We're converting a 69 Charger to a Hemi RT Clone, we're on a waiting list for the 528, heard about this overheating problem and are now considering the 472 instead. The original plan was to have two four barrel carbs on the 528. Guess we could do that with the 472. But would sure appreciate some input from people who drive these engines.
