Rocker bolt torque depends on which bolts you use. Stock bolts are TTY and should be replaced when you remove them. The spec on a stock bolt should be x ft lbs plus x degrees. Reusable bolts are torqued to 25lt lbs.

On rotating the motor. I do. Obviously some of the valves are compressed and some aren't. Therefore...while you will typically end up with goood torque across all by just torquing, I have found one or two cases where rotoating the motor helped torque evenly.
