I have never needed the delay in practice, either (I use mostly NC7SZ, 
74AC, and 74HC logic).  Modern logic is vastly more forgiving WRT setup 
and hold times compared to the bad old days.  I showed the delay just in 
case someone built it without and it didn't work.

What specific chips did you use?

Best regards,
