PROBLEM TO BE SOLVED: To provide a cylinder head design support method and the like capable of improving design efficiency and development efficiency independently of a difference in engine types of a gasoline engine and a diesel engine. SOLUTION: The cylinder head design support method comprises: a common portion selection step for selecting portions (an injector, a valve system, etc.) having common specifications independently of a difference in two engine types between the gasoline engine and the diesel engine; a different portion selection step for dividing portions (combustion rooms, suction ports and plug insertion parts) having different specifications in the two engine types of the gasoline engine and the diesel engine as units and selecting portions corresponding to each engine type from these portions; and a cylinder head model setup step for setting a cylinder head model of the gasoline engine or the diesel engine on the basis of the portions selected by the common portion selection step and the portions selected by the different portion selection step.
