Different foundries with different patterns?

Charles

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
