@cozzy,
The 767 only gets parked on the East 'Cargo' Ramp if there isnt the space on the Central Ramp. The reason for this is that it arrives first thing in the morning, often before the EMA based aircraft have left on their first daily departures. Since bmibaby left I've not seen it parked on the East Ramp yet as there is more space on the Central (even more so since RyanAir sent 2 airframes to Alicante for the winter)
As the 767 takes ULD pallet based cargo/bag loading rather than 'loose bag' loading on the 737s they can easially load any cargo on the Central (in fact even UPS has at least once been required to do a full turnaround of a Cargo 767 on a Central Ramp stand when things went Pete Tong with aircraft going 'tech' on the East Ramp
