which means that it will have a CISIZE of 4 KB (4096).

There are exactly 180 4K blocks (CIs) in each 3390 CYL.

Not true. However in was true in The Very Old Days.
Nowadays CISZ=4k is default for LDS, but not the only choice. It can be any multiplication of 4k: 4,8,12,16,20,24,28,32 kB.
So, the assumption above is not safe.
