* NOTE 1: Tighten center two bolts to 100 lb/ft, and tighten the remaining bolts in a spiral fashion

** NOTE 2: DO NOT use Loctite on Aluminum threads. I have read that it may destroy the threads upon removal, due to Aluminum's softness (and it just kind of makes sense...)

*** NOTE 3: After torquing all bolts, let stand for 20-30 minutes. Gaskets will set in this time, which will require a retorque

**** NOTE 4: Only START the Intake Bolts. Torque Timing Cover to Intake Bolt first, THEN torque remaining Intake Manifold Bolts
