The kids on 2nd Ave between Geary and Anza played a very similar game like Heats in the early 60s, however, we called it Witch. The witch hid and then sneaked up on you and tagged you. You then became the witch's prisoner in her castle, which was a house between the 2 teams. Each team then tried to rescue the prisoner(s) out of the castle. Great fun. One of the kids, Irene Rybalchenko, was the best witch ever. Clever and stealth.
