Fiat Punto Bj`07 1,4L Machine Head gasket change

Hello together, I had to make the head seal again shortly at a 1.4er Fiat Punto year of construction 2007! Since I am not yet familiar with Fiat yet, here a few questions about it: Is everything very expensive in everything or how long does it take approx. need special tools or is this enough for the standard equipment? what should you do everything new in this train? maybe even someone has a rep guide for it and could send me the few pages possibly? Cost point approx. in the works statistics t? parts? reward? would be great if you could help me further, am grateful for any advice! Thanks and greeting Alex
