If I was in your position I would go ahead and do a rebuild on the entire top end since you have to take it apart anyway depending on how long it was since it was done last or at all. This is to prevent having to tear down the top end again in the event that something else goes amuck soon after your gasket replacement. Think of it as preventative maintenance, might as well do it while its apart because it always better than taking the motor apart again, espicually for something small.
Things I would do if I were you:
1. Top End Gasket Kit with all gaskets and oil seals, including valve seals.
2. Hone Cylinders.
3. Replace Piston Rings (5 piece not 3)
4. Clean Intake and Exhaust ports of Carbon Build Up (I use Talstrip)
5. Check lobes on cam to make sure they are within limits.
6. Replace Timing Chain
7. Check Timing Chain Guide for excessive wear.
8. Check Valve Seats
9. Clean and Inspect Valves (Replace if Bad, Usually are good unless something went seriously wrong)
10. Relap Valves
11. Inspect Cam Journals
12. And I would also go ahead and take your oil pan off while motor was out, clean it well, check the primary for wear, and replace the oil pan O-ring (trust me its woth replacing this $4-$6 O-ring while out, rather than getting motor back in with old Oring reinstalled and realizing it is leaking and having to take motor from frame again.
13. Also a great time to really clean the grit and grime from the motor and repaint it if you prefer.
14. Another suggestion would be to replace all crappy Phillips head Screws with a Hex Bolt Kit. There are some really good kits out there for cheap, and will save you many headaches dealing with those phillips screws.
Hope this helped and wasnt overwhelming, again these are suggestions and you do what you want, also I might have missed something so guys help me out if I did its early and I haven't posted in a while.
