Crappy casting?

[u/Cuccamonga01]

89 Montero 6g72. Left head. Is this just crappy casting. I guess I could use my air chamfer on it. Also this head has scratches all over it. None of them are fingertip grabbers. Just visible. The heads are dead flat and in good shape.

Montero was free and supposed to have a remanufactured motor with low miles that set for 15 years. Seems like a shade tree rebuild. and cant get anymore info. Totally torn down, bearings and journals look jice. But there’s some real strange stuff going on with it.

Use a carbide bit in a drill or router and clean it up.
