Do you need rocker stud and spring upgrades on afr 165s?

Thanks again Rick for your help. I will buy a set of 6.25" pushrods then if that's what you have found to work the best. I will either be using harland sharp or crane gold race 1.6 roller rockers with the ARP rocker studs. I appreciate the help because I wanna get this thing going in the next couple weeks.
