I have a nbs 07 with the 6.0 max pkg and L92 heads. There is a set of LS7 rockers ($150) available that will supposedly let this rev another few hundred rpm's.

I'm wondering if it's worth any measurable hp? Work with the magnacharger?

 

You're fine with stocks. Unless you're doing past 7K you'll be good.

 

if you dont buy them send me the link lol !!! so i can check them out, gonna swap lifters when the lxs-r gets here
