Passenger HP Manifold fitting?

Okay, so I hunted around and I think my power steering box is chanting the engine over slightly. It is mashed right into the drivers side engine mount. Can I take out the unit and clearance it a bit with the die grinder or are most guys going manual when they go Big block?
You need to grind the k-frame and not the steering box. I’m surprised that the instructions for the motor mounts didn’t mention this.
