Long story short, I bought an 1811 with a (turns out to be) more or less bad motor. So I looked around and found another used M18. It starts right up and "sounds" better than the previous one, however I want to do a little preventative maintenance on it before I throw it into the heat of this coming summer.
What I'm going to do is remove the heads, clean them up, and put new gaskets on them. What I'd LIKE to do is lap the valves and make sure they're getting a good seat. The process sounded intimidating until I did a bit of looking up on it and found this guide (I know it's not for a Kohler but the principal should be the same):

So that leaves me with a few questions:
Is this a good procedure to follow?
Should I replace the valve springs or anything else while I'm in there?
I've read about grinding the valve stems, is this something I'd need to do or even worry about?
Any other advice/suggestions? I've got the old M18 sitting around I can use as a "practice" motor before I get into my good M18 so I won't be going into it totally blind. Thanks in advance guys!
