From the looks of it, should be ok. If you can feel the grooves with your finger then it needs whats called a Line Bore. That will solve the problem. That normally occurs with poor lubrications, IE- low engine oil level at high rpm.
Good news, well to me. I went over to a local machine shop and the mechanic there told me it wasn't a big deal but I still have other problems lol. Distributor holder is broken, and need new studs.
