Gusha asks in post #11: even has hexagons on the surface of the cylinderheads. But why do they always appear as a pair?

I didn't look at the specific picture but I suspect what you see are threaded caps which provide access to the valve heads. A necessity on engines where the block and cylinder head are cast "en-bloc", that is, as a single casting w/o a removeable cylinder head.
