I'm guessing the State used Fords for two years.

In Minnesota, 428PI contracts were won only in 1966 and 1969. Dodge and Chevy won other years.

If your State used Fords in 1966 and 1968, it's reasonable to believe an engine from 1966 got swapped in during a rebuild cycle. Rather than sidelining a car, the procedure at some shops may have been to jobber out the mid-life engine rebuild, and plop the freshly rebuilt engine into whatever patrol car needed it at the time.

The date code on those heads is 1966, though the -U heads were also available in some early 1967 cars, but it really was a crapshoot in 1966 and 1967. During these years you could find C6AE-J, C6AE-L, C6AE-R, C6AE-U, C6AE-Y, C7AE-A, and fleet cars (like cop cars) even got piulot line C8AE-H heads which were apparently marked "C8AE" without a suffix. This represents four distinct casting styles, though the three emissions styles were quite similar.

1968 was a simpler year, as early engines may have had either C7AE-A or C8AE-H, but later on in 1968, through to 1971, C8AE-H was the sole casting number to be found on FE heads in cars and pickups.
