Bit late to the party on this old post but lowering the floor beams would have been impossible as they have to attach to the fuselage sides exactly on the joint line between the upper and lower bubbles, placing them anywhere else just wouldn't work. A more likely explanation is that the floor was raised by 2 inches when the roller floor was added on top of the existing beams.
The 90027 Sht 2339 is the Vickers part number, 900 being the Vanguard prefix, and W905 is the BEA parent workshop designation.
