The Cambelt snapped on my brothers zvh fiesta rst on Friday and it's wrecked His stg3 cvh head! The head itself is fine but the cam, valves and the lifters are all knackered. I have a 130bhp xr3i zetec engine in my garage and was wondering what would be involved to fit the Zetec head onto his zvh bottom end. I see there are some bung's in the front of the block (oil or water?) which would need removing. What exhaust manifold would I need and would the fiesta inlet manifold fit the Zetec head?

Any help much appreciated
Thanks Billy
