I think i used POR15 engine paint. With a brush....would not do that again. Thought I could save some time by brushing instead of spraying. I wish i had taped the whole block up and sprayed it. My last engine i sprayed with whatever white engine enamel was at NAPA.
I went with .0021" on the bottom, because that was what they came out of the box at lol. And then .00185-.0019 for the top ring. A little loose, but should be safe.

This is the head I spent hours assembling 
And yeah I assume I will helicoil it. Either need to dig up the kit I might have somewhere, or go shopping.

I've never actually used a helicoil. So that will be fun.
I'm waiting on the pump from Travis anyways. And haven't heard from him so I probably have all weekend to fix it.

Helicoils are awesome. I'm going to helicoil a lot of fasteners on my next engine where strength is a concern. Will do all the aluminum threaded things since those strip easy. They aren't hard to do either, just make sure you are using the correct size drill for the tap it includes, and keep the bit straight. Since you're drilling a cylinder head I would set a mark on how deep to drill into the head so you don't accidentally turn that head into a paperweight.

There are still threads deep down it looks like. So I just need to find some helicoils that are long enough.
Well thankfully I take lots of pictures, and have a very observant friend. Can anyone spot the difference?
