my buddy blew his motor in his 90 accord.... he thought he had an f22a1 ( never looked at it or cared to) but i thought he was wrong but he insisted ..... any way he went and bought a f22a1 block and wants to do a head transplant i know its possible but is it just bolt up and go?? or will he have to do something with his ecu or what problems do you think hell run into thanks....
