I've replaced a headgasket on a 93 2.0 litre it took a few days cuz I wasnt in a rush but I counted 5hrs. total.You'll need a valve cover gasket as well as a headgasket.Dont take the intake off,leave it on the cylinderhead.Just leave the timing belt on so when you lift the head off,You'll lift it from the other end and the belt will be falling off from there.For $70 I did it.You may take it in but it costs alot like up to$700.
