My stealer is not up on the 4 stroke at all. When replacing the valves with OEM ones what prep work to seats or anything else needs to be done?

The seats must be refinished by machine cutting, or preferably by precision grinding to restore their original angle and finish. This is a critically important, specialized task that should only be done by, or under the supervision of, an experienced machinist.

If using Ti valves, they should NOT EVER be lapped.
