well its a good idea i heard just cause the top of the engine will be the first to not get oil in the event of a issue and as a result not only doe you kill the engine but the turbo tiny bearing would go dry quicker too is the argument
ive got a tech supliment at work about all the stuff they done to the 200 block engines compared to the 205 and the reasons for it but there was no real pointing argument for this i recall
but they did use the 500 water pumo and thermostat in the 4x4 engines hence the price difference
