Perchance those heads are...aluminum ? Very subject to corrosion, if so. Would also guess that the block is also aluminum - given the very low torque values for the head bolts.

Aluminum stinks as a metal for internal combustion - especially if ANY steel, iron, cast iron parts are used anyplace on the engine = even steel head bolts and steel piston rings. No matter what the auto makers try - overcoming the 'cathode/anode' problems of dissimilar metals, especially under high heat and temperature- can NOT be done ... not in any affordable and long lasting way.
