The sprint doesnt have the same problems because the studs are submerged in oil

Not correct, only one is.

Submerged? Not exactly! But the point is that ALL the studs and nuts and the head bolts on a Sprint are under the cam cover, protected from the elements and (hopefully) splashed at least with oil, whereas on an 1850, TR7, or Stag the tops of the studs and the nuts and washers are out in the open, which allows atmospheric water to permeate the joint and eventually to enter the stud tubes and corrode the studs. It's not so much galvanic corrosion that is the problem, the Sprint proves that, it's one of good old fashioned RUST!
I probably did my first Sprint head gasket in 1974 and have done uncounted numbers since. Never ONCE have I encountered any difficulty getting Sprint studs out, usually by the time honoured method of double nutting them. Stags, 1850s and TR7s are a totally different proposition and one I still, after all these years, approach with trepidation!
On a purely personal note, I don't think i'd be inclined to use stainless studs, simply from concerns about their strength, stainless has different properties to mild steel and reacts in different ways to heat cycles etc.
Surely it would be easier and a lot cheaper to merely put a film of silicone on the underside of the head nut washers to stop most of the ingress of water into the stud cavities. The NEXT head gasket will be in so many years that it will be SEP, (somebody elses problem!)
