Anyone have issues with the Pro Topline rocker studs? I need to get guideplates and rocker studs for my Pro- Topline Torker heads and wondered if anyone had part#s or suggestions on what to get. I would like it to work with some non self aligning roller rockers and hardened push rods if that will work. I read somewhere else that ARP screw in studs can be an issue with these heads but hoped someone had some better insight.
