    right results are. if you use a 1.4 sri head you get a compression ratio of 8:! and a 1.6 head you get 7:! both of which are miles off the mark. if you can remove 7cc from the 1.4 head volume then it will take it back to 10:1

    i think we are going to have to make another article to add to this one now as options have just opened right up for the 1.2 engine from a little conversion
