Isn't it good practice when installing new pistons/rings to get it honed, so the rings actually bed in and create a good seal?

OP makes a point of doing everything wrong and backwards. Don't question it, just enjoy the show

I mean... Did the old rings really have enough time to break in the cylinder walls?

Jokes aside, if OP was pressed for time, he coulda just dingle balled it.

Negative. Dingle ***** and cromo rings are a no go. Look to the plateau for answers.

I thought that the plateau hone was just a finishing technique that could be achieved with a ball style hone. Would be hard to do yourself with a drill fitting hone, sure, but that's what my reading led me to believe before I got my motor built.

edit: unless the dingle ball hone doesn't fall into the category of ball style hones because it's on a drill instead of more purpose built tooling.

Agreed Schroedinger, harsh.

Elior - we will learn more from our failures than we will ever learn from success. As a scientist/engineer - I never see papers discussing various attempts (which end in failure) in the literature. Unfortunately, that means all of that knowledge/experience is lost and we are all left to make attempts at dead ends. If more people would document their path/process and failures we would advance at a much quicker rate. In so many words I'm saying thank you for sharing.

Oh so logic wouldn't tell you that low oct and 20psi of boost would result in failure?

Oh this website I've learned that it is bad to leave rags in your engine. It is bad to have negative valve clearance. It is bad to have your friend balance your crank in his garage and it is bad to take advice from people who don't know anything. All of those pieces of information are valuable and you are foolish to believe otherwise.
