    Hi,
    You have to purchase the repair manual to actually get the factory pattern. I do have a rule of thumb, however. After surfaces and threads are clean, begin with the hottest spot of the head. This will be the bolt nearest the exhaust valve. Notice which will be the next hottest, but move directly across the head and torque that second. Step to the bolt beside it to the one opposite that next hottest bolt and torque it. Jump across to that next hottest bolt and torque it. Jump to the bolt beside it and torque. Jump across and torque. Repeat until all are torqued.
    I would torque to 185 in-lb in one third increments.
    Peace,
