After removing the head I've inspected the cam followers. You can't see much in the first picture, but it shows all the followers.
The next two pictures show the two followers that have the small cracks in them, follower #3 and #7, which are above cylinder's #1 and #4.
The bottom end is o.k. (no bent rods) since all the pistons get to the same height when turning the crank.
