Crane is changing the design of their mopar rockers and shafts....Comp rockers and hardware is available, just get shafts and assemble them yourself.
Comp won't have shafts for a while...
HS rockers IMO, and from what little I see of them, have a not so great geometry...they like to hang off the edge of the valve tip.
Haven't tried any of Hughes stuff yet, but I have tried Racer Brown's rockers and they are very nice!!
