I agree with the statements made by Arm out the Window.
The onice is put onto the owner and/or operator but in saying that the pilot should be willing/professional and aware enough to seek and want to seek out the differences.
The flying bit is the easy bit, but you have to get into the air first. ie; Flight Planning, W & B, Normal, Abnormal and Emergency procedures. These all very slightly between all models of the B206 and B206Ls.
Be curious and seek the information. The result will be, that you will feel more competent and comfortable while flying.
Have fun
