Brent - curious, how does detonation cause the ring gaps to all line up? I know rings move around but trying to figure out in my mind the connection between the two.

My guess would be its not necessarily detonation lining up the ring gaps but excessively high cylinder pressures which you would get with detonation. I know on a blown nitro engine after a 3-4 second run almost all the ring gaps will be lined up when I pull the engine apart. I have even ran them on the trailer and had to take them back apart for another reason and several of the ring gaps would be lined up after just a few minutes of idle time. These engines have an insane amount of cylinder pressure and are on the verge of detonation all the time.
