How to Have a 4G63 head rebuilt.

[Dericsh]

After a head is glass beaded like this, is there anything that should be done to the cam journals to shine them back up before running it again?

A heavy coat of grease or even blue tape should have been applied first, but you can shine them up with a light pass of 400 or 600 sandpaper, dont go overboard,
