on the gti manifold the studs at the bottom have broken off. I can replace them with some grade 8 studs. Should I use stainless studs? I was thinking of using just grade 8 studs and making up some brass hex nuts, but twice as long then usual nuts. Or should I just stick with the grade 8 studs and steel nuts.....?

Stainless is weaker. Trust me I've seen enough busted ones fixing outboard motors... :x
I'd stick with grade 8. :wink:

Stainless also expands more with heat
- not a good result on exhaust manifolds

Go the brass/high tensile option!
