It's 85 INCH-pounds. Unless you have a in-lb torque wrench, the next best thing is "wrist tight" with a quarter inch drive socket and ratchet. They don't have to be killer tight, just enough to compress the gasket a little. Recheck them in a day or so in case the gasket takes a set.

Tightening sequence is not important, but if you are worried, start in the middle and work out to the two ends.

inch pounds divided by 12 is foot pounds so 7 foot pounds.

Very few ft-lb torque wrenches are accurate at readings THAT low. Its best to do "wrist tight" if you dont own an in-lb wrench.
