Answer
Mike,
All cars are different.  You didn't mention the model you have, so I can only provide general info.  Most head bolts get torqued in a certain pattern and should be torque to between 75 - 90 ft-lbs.  Because performing this job can be quite labor intensive and required removing the timing belt and several components, I do not recommend anyone doing it themselves unless they have a experience and a factory service manual.  Some engines can be very tricky.
Good luck!
