hi everybody need help and info, i want to convert or upgrade a 600d to a abarth,

There is no such thing as a 1958 600d; the 600d debutted in 1960. You either have a 1958 600 (no "d"), or a later-year 600d.

what parts of the motor are advised to keep and with regards to the gearbox is there a specific conversion kit or is it advised to change the gearbox, head, weber carbs and what size is twin port 36 ok?

  You first need to define if you have a 600 or 600d, as they have different engine, gearbox & rear suspension/brakes. Some parts you keep, others you replace. Also, which model of Abarth are you wanting to "upgrade" your car to? 750? 850TC? (Stradale or Corsa?) 1000TC? 1000TCR? All have different specs & thus different parts & trim.
