Either way, in my mind, if one broke, the rest are subject to breaking as well. If it were mine, I would be changine all of the studs with good known studs such as ARP. Of course that would be after I checked for the cause of the first failure, and corrected the issue.

BTW Does the engine have a roller cam as you were told it had?

I never opened the intake yet so technically I guess I'm still in the dark about the roller cam. I'm going in the morning to pick up rocker studs and maybe guide plates, prolly some poly locks since there is a bolt busted inside one. I also need to get more oil catch pans or dispose of some of the ones I have so I can drain the coolant. I'm definitely curious as to what broke it too. That's what I was thinking is well if it broke they most likely all will but he said it was prolly a fluke... Idk. If I do the guide plates, I might as well do all new studs. If the lifters or push rods look bad I'll have to grab them too. But I'll have to drain the coolant and pull the intake first. So much for not turning the motor over. I don't want to half ass it but I don't want to purchase new everything either. I think my rockers can be rebuilt, I might rebuild the one that came off, it's faint , but I can kinda feel a slight friction or rough spot on the roller tip. Maybe it's fine tho. I considered going to 1.6 ratio ... I don't know if I should push it tho.

Sorry to hear about that man! Glad you found the problem or part of it! T.J.

To install guideplates, the stud bosses will need to be machined down to compensate for the thickness of the plates, plus they need a perfectly flat surface to seat against.

At this point I would discourage stepping up to 1.6 rockers. Until you sheck your clearances, that could just compound your problem.

I would also check those pushrods for straightness, before reinstalling them.
