The intake and exhaust ports are 1.90” and 1.60” respectively, both a larger size than the stock valves, which results in increased power. The combustion chamber features an advanced, modern design for greater mileage potential and improved efficiency. The rocker stud bosses have Heli-Coil threaded inserts so no damage occurs and the torque load is properly dispersed. For extra protection from wear in your engine, there are hardened spring cups between the valve springs and casting as well. These fresh Edelbrock E-Street Cylinder Heads are not compatible with the Hydraulic Roller Camshafts and must be used with hydraulic flat tappet camshafts with .550” of max lift.
