peugeot 106 – new head screws?

Hey people, actually we wanted to leave our peugeot 106 44kW already, since it is already quite out of the cylinder head gasket, and we have at the moment a car too much. But now I want to change the cylinder head gasket myself… Do you always need new head screws? I will take the gasket from ajusa. costs about 28 euro a screw set so around the 35 euro. I want to spend as little as possible… Tooth belts I would normally have to get a new one. I have 4 new Continental summer tires from 2009, 2 new winter tires… otherwise he would be gone anyway… the pug is already a cheap car
