The Edelbrock E‑CNC 225 Small‑Block Chevy cylinder head (#61205) is fully CNC‑ported for maximum airflow, targeting high‑performance street and racing applications. It retains the stock 23° valve angle and intake flange bolt pattern for use with 1986 and earlier intake manifolds, uses 7/16" studs and angled spark plugs, and can deliver a substantial horsepower increase over Performer RPM cylinder heads.
