Both of the plastic covers (3L) are taller. No I do not have any measurements handy.
For reference (since some don't know & search purposes)
The 3L cover do not work on the CDW-27 platform for several reasons.
The oil cap location, No coil pack mounts (COP) or incorrect coil pack mount (non-COP), and no IMRC mounts.
They are just too tall compared to the 2.5L valve covers.
The other differences are not issues.
The 3L covers use completely different gaskets. They are not interchangeable.
