In the 2006–07 NBA season, he averaged 10.8 points, 3.2 rebounds, and 2.4 assists as of April 15, 2007, and proved his worth as a valuable reserve player for the Houston Rockets, especially in light of the absences of Tracy McGrady and Yao Ming due to injuries.
He had a streak of hitting at least one three-pointer in 37 straight games that season, and established himself as a reliable clutch shooter, making several game-clinching shots late in games.

Head was 10–13 from the floor, 7–9 from the 3-point line, and 3–3 from the free throw line.

On February 19, 2009, Head was reunited with his Illini teammate Brian Cook, after he was acquired from the Orlando Magic, but the reunion was short lived, as on February 28 the Rockets waived Head.
