Scratched Deck Surface

I will get some pictures of the scratch to you guys as soon as I can. Keep in mind it's just a scratch and not what I would consider a gouge, I can however catch it with my thumbnail. If it was a cylinder wall though, it would probably have to be bored. I hope that gives you an idea. Food for thought.....When I worked as a Motor Transport Diesel Mech in the Marine Corps years ago, we used to use an abrasive pad on the end of a die grinder to clean up the deck surface before installing new heads and gaskets. Just so you know I'm using a FelPro composite gasket and Stealth aluminum heads.
