Harley Automatic Compression Release questions

Putting big bore kit in my 103 twin cam and changing ACR from old heads to new heads and have a few questions.

Can I reuse copper washer gaskets? Harley doesn't list them separately from ACR.

Do I use antiseize on ACR/cylinder head threads or go with HD manual's recommendation of blue loctite.

ACR had copper antiseize on them. No sure how blue loctite will work on a part subjected to combustion temps, but hey, I didn't write the manual.

BTW ACR socket is pretty easy to make from 13/16 socket. Don't pay $100 for one.

I know on cars and trucks you're not supposed to reuse copper washers because they are supposed to crush a little when they're installed. If they're reused there's a high possibility of a leak. That being said I've reused them before and it was fine. See what they look like and then decide.
