I do not know to what extent the changes for the TD development were 
implemented in the production line of the n/a motors.  I will say that the pre-chamber 
inserts are dimentionally different, not necessarily functionally so, but 
would indicate other differences as well.  The bare castings are the same part 
number for both n/a and TD now so one would assume that they are to TD spec.
