Doing a ZVH Conversion on an RS Turbo?

Just wondering really, as i have the engine out of mine at the mo and im swaping over to EFI OFAB Managment.

I was looking at the engine thinking to myself... (If i put a 2.0 litre bottom end on this no-one will know because the head stays the same)

Cunning.... Cunning like a Fox, i thought.

So what needs to be done? Is it quite simple or are we talking more of a long thing?
