The Edelbrock E-CNC 225 Small-Block Chevy cylinder head is fully CNC-ported for maximum horsepower and torque in high-performance street and racing engines. It keeps the stock 23° valve angle and intake flange to work with 1986-and-earlier intake manifolds, uses 7/16" studs and angled spark plugs, and can deliver a substantial gain over Performer RPM heads. Made in the U.S.A.
