Bob, if you fully screw the plug into a late 12 port head on your  
bench, and the look at the combustion chamber, you'll see that  
although the plug is fully seated & sealed, there are still exposed  
head threads between the end of the plug and the chamber.
I.e. The plug doesn't protrude into the combustion chamber fully as  
per every westlake head design. Therefore it needs to be fired earlier
I'll try and take a pic.
