I was only trying to share my experience. When the engine is rebuilt with forged internals and sleeved, I will continue with the mods and testing. I see no need to share my results as it seems everyone already knows everything.
Your conclusion that it happened before your mods seems questionable, as does the metalurgy of your picture. If your engine was stock, it might be more interesting.
I suggest you drop this line of "reasoning" in this thread.
