Installing headers - use anti-sieze?
really ? man, i've taken apart many headers, and a few that have been on the
car for 10's of thousands of miles and have never had an issue.
you just put a tiny dab on there or what..?

The GM OEM black oxide bolts have some yellow paste pre-applied. I believe it is anti-sieze.
I used those new bolts from GM.
If not those, I would use anti-seize with dis-similar metals for sure (or high heat applications). Apply about as much as the volume of one pea to the end of each of the bolts.

I've disassembled to many engines to count and had to many exhaust bolts/studs break off. It's not so hard to remove the broken bolt/stud from an iron head but aluminum is a pain in the *** because it's easier to mess up the threads and then it's even harder to repair. I would certainly use anti seize if it were mine.
I always use either antisieze or something arp's bolt lube for stuff going into aluminum that does not require locktight. Probably most important when using stainless, as I've had stainless fasteners gall in both aluminum and stainless more than any regular steel bolts.
