I'm sure you'll get many answers, but I'll put in my two cents.

I use a very thin layer of Curil-T on both sides of the copper gasket. But it's perfectly acceptable to install them dry.

I would NOT use 574, as it harden. With all the expanding and contracting going on there, that can lead to cracking and flaking of the hardened 574 down the road. I've seen it on motors I've disassembled.
