Scott,Throw the spes away,Ive redone several of these.I have used plastic gague and set the rod bearings at .004.But cowman is right add or remove shims as needed while cranking the motor.Try to keep the shims seperate and put them back as they come out,this will give you a good start.as for rod bearings tighten them tight and install cotter pins.After tightening a few you will get a feel for the torque.I torque the head bolts at 90 lbs run it for awile and tighten each one just a little more.With the motor complete in the tractor a torque wrench wont fit in some places than use a wrench and go by feel.I was told by a person that visited the assembly line several times that he never seen a torque wrench in the factory.
