The Edelbrock Victor Jr. 23° 220cc cylinder head for small-block Chevy is a complete head for hydraulic roller cams, offering CNC-machined chambers and bowls, angled spark plug holes and the stock 23° valve angle. With a 64cc combustion chamber it yields roughly 10.0:1 compression in flat-top applications and can support 530–580 hp potential, making it suited for budget-minded builds that still use a stud-and-guide plate rocker system and earlier-style intake flange patterns.
