[TR] Copper head gasket: Which side up?

Smooth side goes up.

It's better if the gasket doesn't protrude, hard to do if the head has 
been milled at all.

I've not messed with the water holes, no firm answer on that one.  If 
the edge of those is rolled over I'd leave alone, if it exposes the 
composite part of the gasket it's OK to open up a bit.
