- Retain Stock Compression Ratio
The Edelbrock #60909 Performer cylinder head is engineered for small-block Chevy engines ranging from 302 to 400 cubic inches, suitable for models up to 1986. This performance head features a choice of 64cc or 70cc combustion chambers, allowing you to optimize compression ratios for your specific application, whether retaining stock compression or enhancing power output. The high-flow intake and exhaust ports are designed to improve airflow, resulting in increased horsepower and torque across a broad RPM range. The head includes larger-than-stock 1.46-inch valve springs capable of supporting most high-lift cam profiles, making it a versatile upgrade for performance enthusiasts. Maintaining the stock intake port location ensures compatibility with standard manifolds and headers, simplifying installation and maximizing performance gains. Additionally, the heat crossover is machined to meet 50-state emissions regulations, making this head suitable for street-driven vehicles without compromising legal compliance.
