The injection head was mostly unleaded but check head for stamped letter in side of head near rear exhaust port

 

The inlets are slightly higher giving a better port angle but the main difference is that the port near the valve has a smooth shortside turn into the valve seat whereas the non-injection Head has a very sharp edge
