yes, a 2.0L head will bolt up to a PRE 2003 2.4....03 and up one oil return passage does not match up and takes some modification...it can still be done though....you will need to use 2.4L head bolts though...the pre 03 head is the same for both 2.0 and 2.4, I am assuming we are talking the DOHC head here...the SOHC will still bolt to the 2.4 but no one yet has found a timing belt of the right size to make it run...although I am sure theres one for some car or another that will work
