Has anyone done this conversion? And what rocker arms do I use. Thank you

 

Without going and looking at it I'm pretty sure your talking about that kit that bolts right into the 5/16 rocker pedestal. There is nothing wrong with them if your going to run a hydro cam. They are only rated for like, around 350 pounds, so you can't run any big spring psi. Any way you stack it, it's still a 5/16 stud. You can run any of the popular rollers.
