Canon FD - gaps between aperture blades

Hi everyone !

I've recently been offered a Canon FD 50 f1.4, SSC version.

The lens having its aperture blades stuck by oils, I disassembled the aperture, cleaned it, and reassembled it, based on this tutorial :

Problem is that since reassembly, I've noted that there are "gaps" between some of the blades. Refer to the picture attached for a good instance of these "gaps".

This is the sole FD lens I own, so I can't tell if these gaps are normal (or even if there were there before cleaning).

Any opinion on how normal these gaps are ?

Thx in advance
