The Edelbrock #77279 is a street performance cylinder head for the Gen V LT4 engine. This head features the same architecture as the factory LT4 head but with a thicker deck, thicker exhaust/intake port walls, CNC’d chambers, CNC blended valve seats and intake/exhaust gasket match for improved flow characteristics.
