In the highly competitive world of IMCA Modified racing, there are few racers who can match Henry's accomplishments. In a career spanning only ten years, the Waco, Texas-based driver has won over 220 races, a record 8 STRAIGHT regional titles, captured the IMCA National Championship, and is currently leading the Modified points. An integral part of Henry's combination, beginning with his first IMCA Championship, has been both World Products' SPORTSMAN II and MOTOWN cylinder heads, depending on which track he's on.

According to Witt, "On big tracks I prefer the MOTOWN heads. WIth the larger ports and valves it gives me extra power to get by other drivers going into turns. On a shorter track I like the SPORTSMAN II heads because their smaller ports and valves give me a boost coming out of the turns.

Witt went on to say, "I've tried other stuff, but in the end you can't beat World Products heads for power, dependability and value." Needless to say, Witt and the 701 car's crew chief Glen Wilson have proven the effectiveness of their combination in spades.
