47 - 60 ft. lbs. put it at 50 to be safe afer the header heats up during a drive do the torquing. you should apply some permatex gasket maker on the gasket to make it leak proof.just a light coat on both sides of the gasket. it's an orange silicone sold at any auto parts store. good luck!

I thought it was less than that. First get the primaries all lightly tightened, then go in order and torque to 27 ft lbs. I'm not sure about this next step. You either torque in order to 35 then go drive around, let cool, and retorque to 35 or just drive around and let cool then torque to 35. It is important to let the motor cool before retorqueing.
Then retorque to 35 again in a week or so, just to be safe.
My FSM is at home. Check se-r.net archives or FAQ for "header install tips"

Oh yea, the tightening sequence is in your FSM or Haynes manual or the install tips on se-r.net
