Although I am not really  offering much of a solution, such bizarre 
measurement results prompt me to  suggest rechecking, just in case 
something about the test setup was  awry.

Well the head is off and the verdict is in.
Cylinder's 4 & 5 had a huge breach between them. Not only was the  gasket 
burned through, the head has a valley burned through about a 1/2"  wide and 
almost an 1/8" deep. Cylinder 5 is clean as a whistle, and the breach  is shiny 
aluminum.
I can't see how this could happen in 3 miles. The car ran fine until the  
last 3 miles, and it hadn't been run hard for some time! The head is  ruined. It 
would probably be prudent to deck the block to be certain of a good  seal 
before installing another head?
I've never seen anything like this. This looks more like an endurance  race- 
many laps at red line type of failure!
