my buddy has an accord with a single over head cam f22 and i was wondering if he could put a s2000 head or and euro accord head on it

 

s2000 is a completely diff engine, so theres no way it will work. the euro R i belive, depending on the year is an h22, which you can fab to fit on.

go to search and type in f22 block h22 head. several threads on it including a couple of guys (prelittleude and pirate) who are running that setup w/a turbo.
