With the head off you're going to want to examine for damage resulting from coolant loss into the cylinders. Check cylinder walls for rust and especially if anti-freeze was in use, check the piston heads for corrosion. Permanent anti-freeze actually corroding thru the head of a piston is not unknown. You might also think about checking the condition of the valves and seats; depending on the prior rebuild and how the engine was used, 40,000 miles could be approaching the time for a valve grind.
