To answer your question, no. If you didn't disturb the cylinder you don't need a new base gasket.

When you unclamp the head from the cylinder, you release the pressure on the base gasket. Inevitably it will impact the gaskets ability to seal. On a race weekend at the track, sure...but at home, with time...its bad practice to not pull the barrel and replace the gasket.

Simply doing so doesn't require you to replace the rings. They spin anyway. And if you're putting them back in the same bore. It makes zero difference.
