hey guys, i have a complete sir F20b head put down with timing belt, headgasket, head bolts, cams w/ camgears and everything sitting. my friend has a dohc F20a in his ascot and would like to know if my sir head will work on his F20a block so that he can go vtec.

plZ do not tell me to buy a complete f20b engine if the swap can work just plz guide me as to what will be needed to do this Frankenstein if it is possible and if it is a direct bolt on.

 

you will have to sort of follow the guidelines for putting an h head on an f block but it may not be perfect since the f20a and f20b is not common in the US where the headswaps have been most documented.
