I assume you have the thicker flange on your exhaust headers. Order these from ARP:

# - Part Number - Size
(1) - 400-8005 - M8x1.25x57mm (4-pack)
(1) - 400-8015 - M8x1.25x57mm (8-pack)

These are 170,000 psi studs and harder than Grade 8, so they will not break under normal use. The packs come with the washers and the nuts. They are expensive but worth it to me since I will never have to worry about rusted and broken studs.
