What Racers Say About CPR

"I have always depended on Keith McCurdy to set up our aluminum heads and to fix them when necessary. Sometimes we are under strict time lines and Keith has never let me down. The heads get done on time and everything always works right once they are mounted on the engine. Keith genuinely cares about his customers."
