No, it doesn't matter. The block size is just a matter of how the data
is transferred between host and drive, and cdrecord or whatever will
write 2048-byte physical blocks no matter what. The drive that
eventually reads the CD back will de-block them as required. It's a
bit like CP/M, if you've come across CP/M's idea of 128-byte logical
sectors mapped onto whatever physical sector size (commonly 256 or 512
bytes for 5.25" floppies) the sytem uses.

But you should be making EFS CDs for IRIX ;-)
