Hit it with a straight edge first to see how warped it is. If you have a mate at a metal shop a skim will usually cost a sixpack. If skimmed go up a size in head gasket.
The important part is any damage between cyl 2 and 3. A little corrosion is fine but if it a massive crater you may be in trouble.
My valves were not burnt or anything so I just lapped them in and replaced the stem seals.
Also shove your hand in the bore and try to move the piston side to side. They should wobble slightly but not heaps. Scoring in the bore will tell you which one is worn the most.
All up, my 'recond' head cost me $137 and she goes better than ever before.
The biggest thing I noticed was the increase in fuel efficiency! With a controlled right foot we get 900+km per tank!! I love it!!
