Best I can tell is AFR might machine the pedestals differently for studs opposed to pedestal rockers. In this case, you're SOL on the Steeda/Yella Terra shaft mounts.

I've heard from some credible sources that the beehive springs have been breaking a fair bit, particularly in the LS1's. I'd be looking for a quality application-matched double spring, paired with titanium retainers. Nice and stable, strong, and lightweight. Guys are turning hydraulic rollers to the high side of the 7000's like this...

If the revs aren't going super high, I'd consider 3/8" studs (possibly with a girdle) as the rockers have a larger trunion and are considerably stronger than those used with 7/16" studs. But again, it'd be best to consult someone when putting the combination together.
