3 dead cylinders before and after overheat

[rangerlocal2]

Oh yes, they're all in there. No ticking or crazy noises that would accompany such a blunder either. .

The oddest thing: Same dead cylinders before and after head replacement. What I attributed to an overheat, may very well be electronic in nature from being covered in scalding coolant.......who knows at this point.

since the ignition fires 2 plugs at once, swap the pairs and see if the dead cylinders move.
