LB9 Water Pump torq specs?

Anyone know what the torq specs are for the water pump to engine block are (LB9)?
It's not in the Haynes manual (although they do tell you to "Follow a crisscross pattern and work up to the final torq in 3 steps").
Thanks in advance.

Torque isn't critical there, just make it snug and call it a day.
