    A question best asked of a junkyard, who will have access to the Hollander interchange information.

    Were I to guess, it would be: no.

    2005 brought VVT to the intake as well as the exhaust - so there will be differences in VVT, and the ECM will be mismatched with the VVT set-up as well.

    2005-2007 heads are interchangeable.

    For compatibility sakes, here is what we know:

    2001/2002: 2001 series intro with standard 2.4T petrol engine. 2002 little changes.
    2003/2004: the 2.5T now standard petrol engine. 2003-2004 are 100% interchangeable.
    2005/2007 - minor engine and exterior updates. New radio and electronics. 2005-2007 parts are almost always interchangeable.

    Keep in mind, most 2003-2007 engine components are similar - Erie VoVo would know for sure. As Astro said - small tweaks were introduced into the 2005 for the VVT. Similarly, 2001-2007 interior components are the mostly the same (i.e. seats, interior molding pieces, accessories etc). And as always, fuel types matter too for engines (i.e. diesel vs petrol).

    Thanks, Ed. Do the VVT solenoids fit in the 03/04 head? IOW, could I possibly use the 04 head while stripping what I need of the VVT from the 07 ?

    I think that this 2004 head is a square peg...why jam it in the round hole that is your 2007 car?

    You need a head? Then get one from the same year car!

    Stop repeating the question until you get the answer you want. Find out for certain by calling Erie.

    I think you're the one prattling on in this thread if you don't have the answer. I asked if it's interchangeable first wholesale, and then in terms of parts. Do you always go and buy what you already have on hand if you can make that work?

    Then do what you like.

    Why even ask?

    As most car manufacturers used same engine block and head over long period of time, the heads can fit but components changed you might can not used or fit on difference MY.
