Default Torque Values for 1990 L98 Intakes

I am starting to put my newly aquired 1990 L98 Vette back together after replacing my fuel injectors, unfortunetely the factory service manual I won on Ebay has yet to arrive.

If anyone knows could you please post the torque values for those 12 (I think) bolts for the intakes. Any help is VERY much appreciated!!

Steve

Default torque specs. . .

the good ole chiltons says 25-45 ft.lbs and also there is a specific sequence in which you are supposed to tighten. its in section 3-14 if you can get your hands on the book. hope this sends you down the right path!
