I have told Junior that any alloy Zetec sumps spotted at the breaker's will be coming home :D

You could well be right ;)

Sounds like a good excuse to finally build that grit blasting cabinet that I have the materials for :)

Anway's back on topic

Use the engine that will best fit in with your long term plans.

If you are going to keep the engine that you first build with, fit the 2 Litre DOHC.
Have a read of Enoch's Blog .... Here

If you are toying with the idea of going the Zetec route at a later date, fit the CVH, it will be so much easier come swap time :)
