Based on Haynes manual, the torque for small block intake is 30. Based on edlebrock instruction, the torque for their intakes is 25, then I guess somewhere between 25-30 is ok based on the type of intake. For head, the torque is 65 for small block (based on Haynes). As far as the sequence goes, I have a picture and I'll try to post it, but for now I can just say they start from the middle and gradually goes to the both ends. I hope this helps.
