Well for the life of me, there are no physical signs of intrusion of water in the engine except. . .
 
A ting of rust in #1 and #5 Cylinders.  The head gasket and the head surface looks perfect.  However, the exhaust valves in 1, 3, and 5 are soaked.  It looks like oil, but doesn't feel like it in my fingers.
 
This thing is kicking my butt.  I have the left side done and buttoned up.  I have to take the exhaust manifold out of the right side now.  Seems there isn't enough room to work as it is, let alone with the manifold on.  It took me all afternoon to R & R  the left head.
 
I'll get some pics later

It's not too clear, but if you look closely, the valves are pretty clean.  Makes me think there is a catostrophic valve guide failure.  I didn't see anything in the cylinder walls and the block surface was less then .02 out of plane.
 
 

 
Tomorrow I'll get the right exhaust manifold off and swap the head.  I should be able to get it at least running again tomorrow.  Before I tackle the timing chain
 
BTW Lea. . .   You were right, there is a cross over tube.  It was neatly hidden.  My Bad

The good news is I finally got to the right head today.  I finally figured out if I take the support bracket off the exhaust under the car, I can move the exhaust manifold enough to get to the head bolts.  I can get to one Y-pipe bolt, but for the life of me can't figure out how you're supposed to get to the other bolt.  Well anyway. . . .
On examination of this side, it was definitely leaking past the head gasket on # 4 and 6.  Possibly #8 as well.  4 and 6 are egg shapped a bit.  You can see where the rings are not rubbing on the cylinder walls.  While it doesn't smell like it inside the motor, I am lead to believe this car was severely over heated at one time.  Probably explains the new water pump and hoses.  This head had water in it though.  That tells me the other side was allot worse.
 


So the cylinder count is 4 with rust in the cylinders and 2 with indications of possible a small leak.  While cleaning the block surface, I encountered a mark between a water port and the outside of the block.  Because of where it was, it was hard to run the cleaner disc on the air drill in that spot.  Blew 45 Minutes making sure it wasn't cracked.
 
I haven't done the straight edges yet, but I can bet the heads are warped if not cracked in multiple places.  My bet is the guides are done on the left head.  The right head looks to be just out of plane.

I just ran a straight edge over the right head.  between .010 and .012 warpage.  There are definite water stains in the combustion chamber.
 
The right side was between .008 and .011 out.  Mostly around the middle and back of the block as the right side.  But I don't see any staining inside the chambers from water.

The block must have a crack in it. . . .  Now that I have put a set of known good heads on it, it's sucking water into #6 and 8, to the point where it's flooding the spark plug.
 
I'll have to open it up again and see if maybe I screwed up, but I doubt it.  These are pretty easy to do.  It's either cracked or the block is warped, in which case there is nothing I can do but trash the car.
