ジンのシリンダヘッド。In a cylinder head of an engine that has an intake passage inclined with respect to a valve guide member fixed to the cylinder head, a valve guide boss protruding into the intake passage is provided at the intake passage side opening of the valve guide hole to which the valve guide member is fixed. The top surface of the boss is formed as an inclined surface inclined in the same direction as the inclination of the intake passage with respect to the axis of the valve guide hole, and is inclined from the center of the valve guide hole when viewed from the axis of the valve guide hole. A cylinder head for an engine, characterized in that the distance from the top surface of the boss to the periphery in the upstream direction of the intake passage is larger than the distance in the direction perpendicular to the intake passage.
