There's a reason why no OEMs use stainless studs or bolts with aluminum parts.
The head is aluminum, and stainless causes aluminum to corrode.
Yeah, it's so simple, that's why so many auto makers have done this...not.
Actually, a lot of OEM exhaust pipes are stainless (yes, stainless DOES rust, just slower than plain steel). Manifolds being stainless is the only good example of cost, being a massive part. They don't use stainless hardware in aluminum because of galvanic corrosion.
Good for them. They're either complete dumbasses or they went the extra mile and have the holes lined with steel thread inserts. Stainless steel threaded into aluminum is a bad idea.
See how they act in 15-20 years...
