If you are talking about the studs that bolt the blower down to the lower intake then I think you may be SOL, otherwise all the other bolts can be replaced with grade 10.9 metric bolts of the same sizes.
Most torque these bolts see really are on the supercharger I believe and thats only 33lbs. Good stamped rated stainless should easily hold up to low torque amounts like used on our upper intake parts. All the Stainless I have purchased so far has the load rating stamped on it. Personally I love the clean look if Allen Bolts. Thank kirst8404 for that idea. He has had his like this for a while with no issues.
