PM on exhaust manifold bolts?

[Rocket Man]

I’ve removed every one that weren’t already broken, then removed whatever broken pieces in the heads that I could, and replaced them with ARP on both my trucks. At least there won’t be any MORE broken ones.

ARP makes stainless exh mani bolts. Best to use their standard steel to prevent galvanic corrosion on an aluminum block.

First off never seize will never last under the heat it's exposed to

There IS a product that will likely hold up to such temps, Mica Lube, from The BG Service Company. Not cheap, but a little goes a long way. Be sure to mix it up prior to use.

It doesn’t say anything about high temp. It says you can use it on spark plugs but you can use any anti seize on plugs. I mean, there are several high temp ones- Permatex copper will withstand 1800 degrees so I’m pretty sure it will do. There’s several more specifically rated for extreme heat.
