so i spend a couple hundo on some cheap procomp 1.6 roller rockers. I know you get what you pay for but i was running out of funds at the end of my build. So i install them and run them with the studs that came with my heads. (3/8) One day heard alot of noise coming from valve train so i took it apart to find a rocker stud tip broke off. I order arp 1.89 studs go to reinstall them and i notice that one rocker is really loose on the stud. Is it possable that they sent me 1 7/16 rocker. It doesnt look worn. Looks factory. Does anyone have a single 3/8 1.6 rocker they could sell me>
