Torque

[mikes67]

Hey folks! I got a 67 Chevelle 300 Sedan with a 402 BB sitting in the frame and I need to know it some one can tell me what the torque is on the Hooker Headers. They are bolting to Edelbrock Aluminum heads, the headers have 2" primary and 3 1/2" collector. I had to drop one to get to the old oil sending unit now I'm going back with it I don't remember the torque.
All help is appreciated.

Thanks
