Head gasket with some holes unopened?

Here I am dismantling an old Hyundai engine: http://fubar.gr/hyundai-atos-engine-2nd-part/

This photo shows the top of the engine block with all the coolant and oil passages. There are matching holes on the cylinder head too: http://fubar.gr/wp-content/uploads/2014/01/13-top-of-the-block.jpg

And this is the gasket: http://fubar.gr/wp-content/uploads/2014/01/gasket-holes.jpg
The red circles indicate places where there should be a hole but there isn’t. Seems like three water passages and one oil passage is blocked by the gasket.

Also this is the original gasket the car came with, not some no-name knockoff.
And some other questions: Looking at the photo of the engine block, it looks like the rightmost cylinder has more coolant passages than the others. Why is that?

Finally, the top middle bolt hole is connected with what looks like an oil passage, and the gasket has this elliptical opening at that point. What is the purpose of this?

The coolant flow in your engine is from the water pump to the back of the engine, then up to the head and forward and out to the radiator. The holes near the front of the block need to be there for casting purposes but aren’t used coolant circulation so they are blocked by the gasket.
That one head bolt has oil flowing to/from the head along the head bolt hole. Not unusual at all.

Thanks!
