You need to buy a manual. Start in the middle and spiral out. Torque in 3 steps. But, you really need much more info from the manual: flatness spec, head bolt torque procedure, valve setting procedure, possibly liner protrusion, etc.
For complete repair information on the 4239 John Deere engine, component technical manual CTM-4 is required.
