It's the angle the valves are at compared to the deck of the block.
23* heads have the valves 23* are the most commonly used on street engines.
18* heads have the valves 18* are mainly used in race engines to get a better angle, and increase flow.
At least that's my understanding.
Bad pick, but you'll get the idea.
