This car originally had the thermal reactors and a previous owner got rid of them.
the stud that came without the car has a reduced shank, maybe for better fatigue properties
some of the other studs look kinda iffy, they're rusty and the thread fit is really loose, or they will be after I clean them
I'm considering replacing all the studs with new and I'd like to get some opinions. The studs from Ace seem OK and in an emergency I'm confident they would work fine.
I'm also worried about breaking a stud if I try to remove them. I don't plan on putting huge amounts of miles on the car but I don't want to have any problems on a road trip.
so should I replace all? are the generic studs from ACE ok? are new studs with the reduced shank needed?

You may find that removing the broken studs will damage the threads in the head or even break off.
Very common on the old thermal reactor engines. There is/was a jig available specifically designed for drilling out the broken stud. If need be, there are also Time-Sert kits that make thread repair fairly painless. 8x1.25
Caveat: Drilling out a broken stud without a jig is courting disaster...don't try it.
