Intake torque sequence

Intake torque sequence
I searched for this on the form and can't find anything. I need to buy a manual! I'm looking for the torque sequence and the ft/lbs torque value for the iron 1973 Olds 350 4bbl intake. Got it all prettied up with fresh gold paint and ready to assemble! Won't be until this weekend though. Gotta work all week. Dangit.
