As m4tt274 says it will have a zetec bottom end so the mounts should be the same.
Obviously you are going to have to built the zvh up using the cvh head off your rs turbo.
As for ease it will depend on how much knowledge you have on the two engines and also how good your are with a set of spanners.
If you arent there are many good garages about that will carry the conversion out.
Hop this helps you out
