Boost is not always indicative of true power but it is a measurement of restrictions so the 4 valve head/intake has less restrictions than the 2 valve head/intake. The smaller 5.2 DOHC is more the equal to cubic inches of the 2 valve 6.2 motor setup so things are more equal than not here so you can't really compare the engine sizes.
