The bored was changed very little and the spacing is the same, But the stroke was increased from 80mm to 91mm making them need asymmetrical connecting rods to keep the engine from getting too big. Yes, the coolant pathes now allow for regular gas and it is said the engine will be at least 10% more efficent than the 3.0.
