Torque all the big bolts to about 24 ft lbs. Then tighten all the big headed bolts 90* farther. Then torque all the big head bolts accept the two shorter ones 90* farther again. Then torque the two shorter big head bolts only 50* farther. Then tighten all the little bolts to 24 ft lbs. Warning... make darn sure there is no coolant in the bolt holes before you start. Warning #2. This was from memory. Do a Google search to be sure and to find out what order to torque them in. Its not hard to find.
