They were also on LS2 engines.

Also on the newer GMT900 5.3s.
The 241s would be your next best option if I remember correctly, but I would think you could find some 243s cheap enough nowadays to make it worthwhile. The 241s don't flow as good as the 243s, but make around the same compression I think. With a good port job, your 241s could flow decently well though. After all, they were used some sweet F-bodies.
Here's a link with a little info, not much.
