It's not unusual for 320 owners to fit a 325 manifold and throttle body to their engines in their quest for power, so this isn't a reliable method.
The only way to check for sure is to check the engine type number, or look for a large 2.5/2.7 stamped on the side of the head.
Checking the ECU label is another clue, but again not conclusive, as a 320 ECU can be 'chipped' to 325 spec.

well its got 2.5 stamped on the side, on one of the welsh plugs, does this meen its a 2.5 please

Check the plug isn't 25mm in diameter.
Never noticed anything stamped on a welsh plug before.
