To my knowledge those are casting lines made when the block was cast. I personally have seen them many times and wouldn’t worry about them. Remember read my signature.

Man those look awfully similar. Other than the one and the two. Sure look like cracks to me. Strange way to put casting numbers on. ????

As I stated earlier, those are not cracks.

These castings are made by a casting procedure known a "lost Styrofoam" casting and it often makes some strange impressions in the aluminum metal surface that can be perceived a faint crack, but they are not a crack. They are literally a pressure seam. Back in the cast iron days they actually had raised flashing seams that machinist had to clean by hand.

You can verify this with a back light if I'm not mistaken but they do not look like anything to worry with, I would be more concerned with the governor
