Do you buy used Nox’s, do the needed repairs, and sell them for a profit? Or do you do this for your daily drivers? I had a relative who purchased used cars, usually dirty appearance but in good operating condition, cleaned the interior, washed and waxed the exterior, then sold them for a small profit. Sort of a hobby. He’d do one car a month. ---

But it doesn’t look like you will need anything as this looks like porosity and it is within the cylinder bore, so no gasket over it. This head should never have been installed in the first place.
