Stage 0 is fixing what's broken, if you're running within spec (that takes some research and some testing) you shouldn't need to take it apart. Getting it there requires what you're doing now ie: fixing leaks, tracking down codes, replacing worn components, freshening up fluids/connections.
Aside from forced induction, there isn't much you should need to do internally if it runs well with no funny sounds or obvious issues.

This getting it to stage 0 is what I'm trying to figure out. Before I did much reading, I figured a rebuild kit would be the way to go. Based on responses like the one by Basslicks at the start of this thread, I don't think so anymore. How do I make sure I get back to stage 0? Also, yes, I plan on fixing the do that? For the record, I've changed an engine before, but never taken one apart. I'm sure I will need to as part of this project.
As for the 0331, does a good compression test mean it hasn't happened yet, and I only need to worry about it going forward? I honestly haven't driven it long enough to know of any coolant leaks yet. I only notice oil on the underside of the car and some on my garage floor. Good oil pressure on the gauge and good temp there too.

No, I don't lick fish.
You can tell if it has the 0331 by removing the oil filler cap and looking down the hole. It's stamped right there between 2&3

Hi double_0_7:
You may read the article "Fix Your Own Jeep" in JP's August 2o18 issue. Good information on how to stop engine oil leaks.

A full detail of identifying whether you have the defective 0331 or a properly replaced one.
Edit - Oil analysis is a good idea regardless of whether the defective head has been replaced or not.
