Would it make any difference on vertically split crankcases? I doubt it, as the seal needs to be pressed or tapped into its bore anyway.

If I remember correctly, the RH side crankshaft seal sits in the rotary valve cover, so that should be pulled off first. I suggest to replace the large rotary valve cover O-ring at the same time, and also the small O-ring on the oil injection "dowel pin".
The LH side crankshaft seal may be tricky to remove on an assembled engine, but drilling a couple of small holes in it, then using a couple of suitable wood or sheetmetal screws will give something to pull on.
