Not Ranked
Are there shims underneath the springs?
I would imagine that the install heights are the numbers that are written on the sides of the heads.
That one head has .035" difference between the shortest and tallest height. Hopefully they corrected it as .030" can be a big difference in spring pressures. I would make sure that some of the valves are not sunken into the seats.
