Valve Spring pressures in the Rover V8?

[Jupiter Rover]

Does anyone know the Valve Spring pressures of the Rover V8? Are they the same from the 3.9 to the 4.6?

Are they high like old muscle car engines or are they more on the low end like the jeep 4.0?

Thanks.

Call a machine shop.

They usually run around 65 psi.
