what's on the header bolts?

[family man]

I removed my factory exhaust manifolds and cats this past weekend. What did GM use on the headers bolts going into the heads? Is that anti-seize or a thread locker?

I must say it was alot easier than I thought to get everything apart. Using an air rachet made it a breeze getting the header bolts out.

There's no need to use power tools to get header bolts out. IMO, it's asking for trouble. It would be pretty easy to strip them out using power tools. They don't require that much tq during the install. I'm thinking it's like 20ft/lbs or something like that. Many people use antisieze while others don't use anything. NEVER use thread locker on them though.

18 lbs/ft but yea, no need for air tools.
