Edelbrock E‑CNC Small Block Chevy cylinder head, fully CNC‑ported for maximum horsepower and torque in street and strip applications. The design maintains the stock 23° valve angle and intake flange bolt pattern for use with 1986 and earlier intake manifolds, and the casting provides extra material for porters. According to Edelbrock, these heads can deliver substantial gains over the Performer RPM head.
