Cat 3204, looking for advice on gouged cylinder wall.

Hi all, I have an early 80's 931B with a 3204 NA in it and about 6500 hours. I use it around my farm, maybe 50-100hours a year. I pulled the head because head gasket went between 1&2. I found these two gouges in cylinder 2. They are deep, can feel them easily with finger. When I pulled injectors, I found that #2 injector was a reman and the others still had the original cat part number.
Now, do you think that tip went on #2 injector and gouged cylinder or is there something more serious? Its always kind of had some blow by and doesnt really use any oil.
