Thanks for helpful advices, Mr PANTERADOUG
We would like to return the original parts to mangusta, but the primary our goal is to run the car in any time and at any place. I know your effort to run. You did weld and finally did change the engine to 347 with shaving the head to give the same size of chamber. How hard effort! Regrettably we don’t have such knowledge and experiences. We will choose the way to look for the head to work well.
