Are the center bolt valve covers interchangable through all the years of the LS1? Are there any difference in the valve covers for 243 heads?

I'm installing some 243 heads for a H\C swap on my 98 C5 and wanted to make sure I get the correct valve covers.

 

Any '99 and up V8 valve cover will work. Even 4.8L, 5.3L, 6.0L truck covers will work as well.

Thanks for the answer! That opens my search up quite a bit.
