There's no single torque specification for a Cummins N14 rocker box. The torque required varies depending on the specific rocker arm bolt and the year/model of the N14 engine.
You must consult the official Cummins service manual for your specific N14 engine. This manual will provide the precise torque specifications for each bolt involved.
Using an incorrect torque value can lead to serious engine damage, so relying on information found online without verifying it with your engine's documentation is extremely risky.
