Slant 6 Vibration

Well fellas, this might make it toast. I wanted to check out the full depth of the cylinder walls, so I went out to turn over the engine and check it out. Attached is a pic of the scoring on the bottom 2/3 of the cylinder. It's not mega deep, but I can feel it with my finger tips. There's about 5-7 strips about 1/4" wide spread out around the cylinder wall.

And in case I had any doubts that little to no coolant was actually making it through the head:
