Dart 11511122P - Dart SB-Chevy Pro 1 Aluminum Heads

The Best Value in High-Performance
Aluminum Heads for Small Block Chevy
Standard Pro 1 Cylinder Heads deliver outstanding airflow using advanced tooling & state-of-the-art casting techniques while the CNC-ported version provides even more "flow for your dough."

Engineered for easy installation as bolt-on replacements for most conventional 23° heads, Pro 1 heads accept standard small block pistons, headers, and valvetrain components. Dart improved the original design with thicker decks and high-capacity water jackets that increase reliability in high-performance applications. Hardened exhaust seats and durable bronze valve guides greatly extend cylinder head life. Sold individually.
