The blocks are different (though exactly the same size), and same goes with the heads.
It's 680mm from edge of head to edge of head, but the front covers of the VH45DE are slightly wider due to the VTC solenoid valve being in the front, giving the impression that the VH45DE is bigger. It isn't.
These differences have been covered long ago, the information is available here on nico... just spend some time browsing through and learning.
