Yes there is a tightening sequence, most likely start middle across x pattern. Check pan for flatness, I usually take piece of wood and support pan area(under bolt holes) and hit with hammer to assure they aren't misshapen preventing a good seal. Don't go crazy with tightening and use a quality gasket. Always start all bolts by hand before any tightening then equal tightness in a couple of passes.

Pan bolt torque is 130 INCH-pounds (11 foot-pounds). You can't use a 100 ft-lb wrench to set bolts at 10 ft-lbs. Torque wrenches are that accurate at 10% of their range. You need an in-lb wrench or, at least, a ft-lb wrench with no more than 50 ft-lb limit.
As mentioned above, start the bolts by hand; run them down to 'barely snug' with a 'spinner' wrench or ratchet. Torque all bolts to about 5 ft-lbs (60 in-lbs), then tighten them all to spec. If you use any sealant on the gasket. Run bolts down finger-tight (no more than 2-3 ft-lb) and allow the sealant to set up overnight. Then follow 2-step torque process.
