Obviously the rings expand from heat. The problem is, if you start out with a .007" or .009" gap cold, then your engine won't be able to withstand the heat that it would if it had started out at a .015" or .020" gap cold. That is why the (varying) problem of the ring gaps in the LT1 is so important to be known. No matter how good the tune is, if you are one of the unlucky ones that slaps a supercharger onto a .007" engine, you will not be able to do the same things that someone who's engine has say .015" will. In other words, a good tune does not actually fix the mechanical problem. It only attempts to minimize the effects of it.
