Different foundries with different patterns?

Interesting Charles, I will dig out all the spare blocks I have to examine them to see if there is any pattern. I have also seen the matching drillings on some crankcases, I will be fascinated by what Tony finds as he obviously has a far larger stock of parts than I do. I guess this is purely of academic interest but I wonder why it was done, as I mentioned earlier I assumed it was to increase valve chest oil mist, however why would the drillings not be consistent???
I've got a crankcase here 209000 with matching holes

In my book the extra holes are solving a problem that didn't really exist.
The block im preparing is a nice screw in core plug one. Extra holes and their matching crankcases are on my "not wanted" list!
