valve guide replacement

[xp190]

I was wondering what is involved in replacing the valve guides.

I am working on an engine, it's not a mercedes engine, but soon I will be doing the same on my mercedes engine, and was wondering how this process is carried out exactly.

This engine I have in pieces now is the Mitsubishi 3.0L V6 commonly found in many Chrysler cars.

I have both cylinder heads off, and it looks like some of the valve guides have "dropped", so I want to fix this up and put the car back together.

Assuming that the valves are still good, and will not be replaced, is it just taking the valve out with the assistance of a valve spring compressor, tossing out the old one and putting on a new vlave guide and seal and putting the valve back on?

Is griding necessary or anything else like that? I will be doing this for the first time, so any hints and tips will be greatly appreciated.
