The Texans opened the scoring when Justin Howard took a pass from quarterback Jordan Reaves and scored from 88 yards out. However, the ensuing extra point was blocked and returned by Heights for a two-point conversion.
Trey Douglas' 12-yard touchdown reception from Reaves gave Lamar a 13-2 lead after one quarter. The Texans added second-quarter touchdowns from Howard and Reaves to take a 27-2 lead into the halftime locker room.
Heights' first TD of the game came on a third-quarter Ezell Williams score.
The winner of this game has gone on to win the district title each of the past five years.
Undefeated Lamar is the two-time reigning district champion, while Heights (2-2) won the title in 2020 after Lamar won it the year before.
