Engine inspection (with pics)

[Licensed to kill]

So, I pulled the head to change the gasket and inspect the cylinders. What I found was zero ridge except for cylinder 3 has just the SLIGHTEST hint of a ridge. Could be carbon. Pistons are .100 over, cylinder walls have NO cross hatching at all. So this is after 300 miles using 5 quarts of oil. Plugs should be a lot more fouled if it was burning that much IMO. The wife was following me the other day and said that it is smoking a bit. I'm thinking perhaps pulling the pistons, deglaze the cylinders, new rings and it should be good. Not convinced that all that oil when through the cylinders so must be leaking more than usual somewhere. Thoughts??.
