Default cylinder head options with MS4

Just was curious to see what all cylinder heads people are running with the MS4 cam and what power they got with their combo. Please say if you had to fly cut or not.

I was told with the MS4 you are very limited to head options. Pretty much have to stick with stock valve size. They said their LS6 stage 1 heads would work but I can't remember if their 5.3 stage 1's have the same valve size? You go up on their stages and the valves get a little bigger. They recomended staying with the LS6 heads.
