Getting ready to install my ceramic JBA headers with Percy gaskets and stage 8 bolts. Anyone know the torque spec? Should I use anti-seize on the bolts? I have both the nickel and the copper permatex.

As a pipefitter, I will tell you that you should never sieze any bolt that is exposed to weather. Just a light coat, don't paint it on. I never sieze my wheel studs as well. Use the nickle based, not the copper based if you have the two. Nickle based is also much more heat resistant. In high heat situations copper based is actually working against you.

Shoulda mentioned that I'm installing a new set of Prothane Bullet motor mounts while I'm at it.

Diabolical!

Mapitts beat me to it. Thin coat of nickel-based antiseize any time you bolt steel into aluminum.

Anytime you are threading into aluminum, you should use a thin coat of anti-seize

Make sure the nickel based is actually nickel and not aluminum based which is useless on aluminum. I have used the copper based for years and never had a problem with it. I rarely have any high heat applications and for that the nickel is best.
