Manifold bolts
I just finished replacing my exhaust manifold bolts with factory stock studs/nuts after 1 broke. What can I put on these, that the exhaust won't bake off, so that they won't rust?
Thanks

I recommend nickle anti-seize. Available in most auto parts stores. I also recommend replacing the bolts with grade 8 (or better) bolts. Apply the Nickle Anti -seize and torque to spec. It is the best stuff I've found.

although I can see the benefit of stronger bolts. I'll look for the Nickle Anti-seize so I don't have these rust out.Thanks!

I would have installed some 300 series Stainless bolts , however spraying some high temp header paint on the bolts every now and then will help keep the rust at bay.
