Finally I take a look inside the intake and exhaust ports and see metal shavings from the valve job, just sitting on top of the valves.

Maybe half a teaspoon full in each port. The head shop just installed the valves and everything and supplied them to me. Its my fault, this was the first head job i've ever done using a cylinder head shop, but i can't imagine how that motor would have turned out if I actually fired the motor up! Thing is, I don't think the scratches are that big a deal, and they will hone out without other consequences. I doubt seriously you could measure the loss of seal with a leakdown tester or compression gauge.

Keep your focus on the valve train problem. That's what really needs attention. Could the scratch be caused by the pin in the ring groove, that locates the ring itself, not pressed in enough??? If your pistons even have these, I might be thinking of motorcycle pistons.

Fixing scratches on wooden walls not only improves their appearance, it helps to maintain the integrity of the wood itself since even superficial scratches create an environment where moisture, mold and mildew can gather and degrade the wood. Most minor scratches can easily be fixed in just a few minutes using a combination of light sanding and wood putty; however, severe gouges on high-quality hardwood paneling should be assessed and fixed by a trained furniture specialist to avoid further damage to the wood.

Fold a sheet of grit sandpaper in half so the coarse side faces out. Gently rub the scratch to remove the tiny slivers found along either side. Avoid rubbing the surrounding wood since it will roughen or lift the varnish and cause discoloration. Brush the scratch after sanding to remove the wood dust and splinters. Use a small, fine-bristled paintbrush to avoid further damaging the wood. Blow in the scratch to dislodge any dust that appears trapped inside.
