I thought the same Tony.
I have seen similar on two engines in the last year - both were bored right out and had high lift camshafts with incredibly strong valve springs (Maxi perhaps?) - I presumed that the blocks were being asked to do too much coupled with thin walls. Neither had done more that 4000 miles since full rebuild.
