Pontiac 3100 Intake Torque

My wife has a 2003 Pontiac Grand Am with a 3100 motor. It developed a coolant leak and we are fixing it now. We had to remove the intake and now that it is ready to be put back together, I can't find any info on the torque for the intake bolts. I know that excessive torque will crack the intake. I have a 96 GMC 305 Vortec that I had to do basically the same thing to and I believe those were like 25 in. lbs. but I can't remember. I know it's not much. Does anyone know what the intake on the 3100 should be torqued to?
