They are all the same engine the only difference is the throttle body is bigger on a larger bhp model.
Also it would cost you less to have a garage change your engine over than to have you car sprayed. If you swap youe engine over rather than change head gasket get them to change your cambelt while the engine is out.
It is cheaper to swap an engine rather than a head gasket because head could be cracked or warped.
different throttle body, cams, inlet manifold & ecu.
