The Edelbrock #60985 E‑Tec cylinder head replaces 302, 327, 350 and 400 small‑block Chevy heads using Vortec‑style manifolds and features an LT1‑style raised runner intake port for improved airflow. A revised combustion chamber places the spark plug nearer center for more efficient combustion and stronger power up to about 6,000 rpm. The head accepts common valve‑cover patterns and supports stock piston compression ratios.
