I think the question becomes what are you gaining by them? If they are a deal - the bearings and tolerances will need to be different for them - so bear that in mind. You won't break them, and it will rev quickly. They do stretch more so again, bear that in mind when you're having the machining done. It's usually cost-prohibitive to use them in a street engine. But I'd have no big problem running them (a brand new set) if they were available. You will not get extended life from them, and you better be very careful because marks on the rods can lead to fractures, but they'll work.
