Can't tell for sure..when I blow up the picture, I lose detail/focus...There are sometimes straight casting marks in the crown of the piston firing area, but never on the head surface between cylinders.
What i see in your pic is a non-straight line between cylinders that continues as a non-straight line into the crown area...looks like a crack...
