Edelbrock Part # 61259 Victor Jr. 23脗掳 220 cylinder heads are designed for small-block Chevy Its 64cc combustion chamber yields around 10:1 compression ratio in a typical flat-top application and about 12.5:1 when used with some of the most common 12cc dome pistons. One of the key features of the Victor Jr. 23脗掳 220 cylinder heads 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 23脗掳 valve angle as well as the intake flange bolt pattern for use with 1986 and earlier intake manifolds. All of this allows these cylinder heads 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.
