All V5s are twin cam . Only difference you can see was early had coilpack and leads while later had individual coilpacks .
All 2.0l 4 cylinders are the same .
110kw v5 also had extractors while the 125kw had cast iron manifolds .
Main difference regards to the power was the extra 2V per cylinder and also much larger ports both intake and exhaust on the later 24V V5
