Broach mark question/thoughts

[ryanchevelle]

Appreciate the comments so far. I don’t think restamp because why wouldn’t you deck the block etc first. This was before they rebuilt the motor too look at the piston. I didn’t think it was a broach mark because it’s only on the pad and not where the head would sit. I thought maybe someone used a file or something abrasive to maybe see the stamp better but the stamp still looks crisp. Def doesn’t make sense, but that’s why I’m asking here. Keep it coming guys
