in my experience, generally, SS fasteners are kind of "gummy", so they can gall up if you don't use a dab of anti-seize on the threads. I agree they are more useful in low torque situations, like valve covers, intake manifold, etc
I was thinking like alternator brackets, pulleys, power steering pulleys, I’m very interested in this CVF serpentine kit. The kit comes with stainless steel bolts.
