The scratch is in the upper third of the cylinder, not on the thrust side. I was going to go grab a pic of it but it snowed and these old bones don't like being cold, so walking to the garage wasn't on my list of things to do.

I'm going to a ceremony tonight (my son won officer of the year) but I'll definitely get pics tomorrow. Supposed to be significantly warmer than 17 degrees tomorrow too. I'm really hoping I can just get by with a good hone and new pistons and gasket set. The cam looks great, just a little discolored where the lifters rolled over it. No scratches.
