Good time to ask.
The process is fairly easy, and will only require a couple special tools. However, ask any good engine builder and they will tell you to measure stuff before and during teardown. This will give you info to help decide what machining and parts you need to rebuild.
Check crank thrust, rod side clearance, piston height, and look at the cam/lifters for any unusual wear. I'm sure some others can give you even more to check.
