this link shows the engine combos (I think I recognise one of my brother's apprentice's name in there...)

The machine ported GT40P heads on the 220kW are the same as the 250kW I think
A while ago I got a copy of the tech specs/service manual on the 250kW motor (cant find atm)
From memory the rocker ratio is 1.7:1 rather than the usual 1.6:1 and The cam lift at valve comes in at about the same as the ford E303 cam

Thanks LoBelly. So the 175kW had E7 heads? So there's at least one of the differences I was looking for. E7s are considered as not worth hand or machine porting. That's more than just a change of ECU to upgrade.
Cheers,
Glen
