Hi there ! Sorry to hear you are having trouble! My name is ***** ***** I would like to try and help if I can ! I am going to say no on that one. They went through so many design changes throughout the years and added EGR and higher turbo boost pressures. In doing so, they had to make modifications to the head to be able to withstand the extra pressure. I believe it would not be a good idea to try this .
