If I understand your questions correctly, you are asking for the assembly head bolt torque and lash (clearance) of the intake and exhaust lifters.

Proper head bolt torque is 65 ft/lb, or 88 N/m. The head bolts must be tightened to final torque in three steps, 30, 50, and 65 ft/lb. Begin with the center bolts and work outward in a circular pattern until all bolts are at 30 ft/lb, then repeat the step to 50 ft/lb, then repeat again at 65 ft/lb.

The lifters are hydraulic type and adjust the lash automatically. The pre-set of the lifters can be done on assembly but the lifters must be full of oil to perform the adjustment. Install the rocker arm and position the camshaft so the valve is fully closed. Make sure the push rod ends are oiled so the push rod can turn freely between your fingers when installed under the rocker arm. Start tightening the rocker arm nut until the push rod can no longer be turned with the fingers, then tighten the rocker arm nut an additional 1/2 to 3/4 turn. This should position the hydraulic adjustment plunger about halfway in its travel inside the lifter body and allow for automatic adjustment of the lash.
