You will need to consult a repair manual specific to your 1988 Ford Festiva. The manual will provide:
* The correct torque specification in foot-pounds (ft-lbs) or Newton-meters (Nm). This will vary depending on the bolt and its location.
* The proper torque sequence. This is the order in which you tighten the bolts. Tightening them in the wrong order can cause the head to warp.
* A step-by-step guide on how to install the head gasket.
Trying to find this information online without a repair manual is risky. Using incorrect torque can lead to a blown head gasket, warped cylinder head, or other expensive engine damage. Investing in a repair manual (Haynes or Chilton are common brands) is a much safer and cheaper option in the long run.
