I purchased a set of used ARP 425s from a member on here...they turned out to be ARP 2000s and there is significant corrosion on seven of the studs. Needless to say, I'm a little p***** that this wasn't stated in the listing, but then again it's on me for not asking the question on a knowingly used part. Either way, I want your opinions on whether or not to use the studs and if yes to using them, where should they be placed in the torque sequence? The ARP website states to replace the stud if there is visible corrosion. Here are a couple of pictures:

I wouldn't use them either, too much risk to be worth it.

BTW, ARP 2000 is the same as 425.

ARP sells individual pieces if you contact them. Could probably get 7 new studs from them for reasonable.

It is worth the $100 or whatever they would charge to have the peace of mind at least.

edit: only thing to worry about is how 7 new ones would mingle with the rest of the old studs. Not sure if stretch or anything like that would play a factor. Not a fastener expert.
 
Mine corroded from years of leaking coolant and eventually broke one.
