One of the key features of the Victor Jr. 23deg 220 cylinder head is the CNC machined chambers and bowls, which result in consistency and improved performance. They also feature angled spark plug holes and maintain the stock 23deg valve angle as well as the intake flange bolt pattern for use with 1986 and earlier intake manifolds. All of this allows this cylinder head to deliver 530-580 hp potential right-out-of-the-box, making them ideal for a budget minded engine build desiring a high quality cylinder head that still uses a stud and guide plate rocker system. , Cylinder Head Specifications:,Exhaust port location: Raised .300in.,Spark plug fitment: 14mm x .750 reach, gasket seat
