Perfect timing: I was about to post a general inquiry about what to use
on fasteners!

One thing not explicitly called out on Scott's rundown (below) is what
to use on the fasteners that hold the exhaust flanges to the heads.

I ask about this because I had to remove a couple last week to pull the
tin off the bottom of one head to access the oil pressure switch. I put
the fasteners back on "dry" and had a feeling that I should have used
some kind of anti-seize. Recommendation?
