"Clock" the rings if you feel like it, but it's a waste of time on anything but a 2-stroke engine where the end of a ring can get hung up in a transfer port- - - - -and those pistons have pins in the ring grooves to prevent that from happening. Rings rotate around the piston all the time, and yes, the gaps do align with each other occasionally (for a few seconds). I had a training engine with a quartz window in one of the cylinders, and I used to watch the rings spin around the piston with a delay-flash timing light set to slow down or stop the piston travel.
