Well, I started the engine overhaul.  I'm going to update my photo album sometime today...

Got the engine fairly torn down.  The block still has the PS pump attached, but that's about it.

Pulled the head...  Coolant in pistons #1 and #6, and the copper rings around the water jackets on the 
exhaust side were deformed.  Basically, I think it's a very good thing that I decided to overhaul this 
engine.

The head bolts appeared to have been re-torqued.  They were damned hard to break loose.  Even if I were 
considering doing so, I don't think that I'd want to re-use them.  I have no doubts whatsoever that the 
head gasket itself was the factory original.

There is a slight ridge at the timing cover at the front of the block, however it appears that the stock 
gasket didn't have any trouble with this in particular.

So...  it appears to be a relatively straightforward head gasket job, though I'd feel more comfortable 
if I didn't need to surface the head.

Halfway there, I think.  Maybe.
