End holes on the head go into the water jacket. If you can, put studs there with sealant on the threads. The rest of the holes are blind.

Nope. -- All are wet.

I have all studs,
I like the white permatex best.

Loctite #567 with teflon sealant. [it's white as well, and can be used in virtually ALL liquid and gas plumbing situations]
i have been using this stuff exclusively for over 40 years, and have never had a sealing issue.
