Do I have a B20a or a B20b? 120-130

B20A is the single-carb, "A" cam version not usually found in the U.S. B20B is the usual dual-carb model having a "C" cam. However, having an injection head turns it into something other than a B20B -- it could be a B bottom end with a different head, or an originally injected engine converted to carbs. The bottom ends are essentially the same except that the injected ones used a "D" cam.
