Head Bolt Torque

Cast iron head 80 ft. lbs. torque in 3 progressive steps. I did 30,60 & 80 follow the torque sequence. rocker arms (hyd.lifters)spin the push rod with your fingers and tighten the nut until there is a heavy drag then 3/4 to 1 extra turn is OK just do them all the same.Make sure the valve is closed (lifter is on the base circle of the cam) I rotate the engine until the intake valve is closed then set the intake & exhaust of the same cylinder at the same time. Be sure the push rod is seated in the lifter correctly.
