Well, the verdict is in. The cylinder head was cracked in two places. One along cylinder #3 and one between the exhaust seat and outer combustion chamber on #4. The shop welded the cracks and we installed it today.

The ENGINE (hot/oil) light never came on while I drove this car and I wonder if it overheated once or is the cracked cylinder head just part of the engine design?

I did use the hardened grade 8 washers under the head bolts, torqued the head to 73 ft lbs. Over the next several weekends, I finish all of the hookups and get this thing back on the road.
 
8) cylinder heads tend to crack when they have been over heated and frozen over a few cycles. some heads have a casting flaw that allows stress risers to form, and some heads are born to crack like the 2.9L V6 ford heads.
 
Seeing how many late model heads seem to have cracks Im tending to think there is a casting flaw somewhere.

Its like the 2.3L OHC heads, its hard to find one that doesnt have a cracked exhaust port.
