one other esoteric comment. newly cast cylinders, and other bits like often contain localized metal distortions and stresses from the mftg process.etc.and then when assembled and torqued down, have additional stress patterns introduced to the metal. It's why torque numbers are Important. now, as the engine is warmed, these introduced stresses try to equalize with each heating/ cooling cycle eventually reaching a relatively stable state which is why master performance builders choose older engines to blueprint for max performance, the machined/designed tolerances are more reliably retained.
Also, the initial cylinder x hatching helps maintain reserves of oil on the cylinder walls as the rings/cylinders mate as it were.
