Have been fighting the exhaust manifold bolts/nuts on my '38 Zephyr v12 flathead. Only been on there for 76 years. When I reinstall, I would like to put them back on with a reasonable chance that I or the next guy will be able to remove without making a sacrifice to some god. What type of fastener material would stand a good chance of coming off in the future without what I had to go through? I also plan to use a copper based anti-seize good to 1800 deg. Thanks
