Did you have one of the plugs fouling/cylinder missing? You may have a bad valve guide seal. This could cause the oil consumption you are seeing. The bad valve guide seal could be caused by a broken inner valve spring. So get the head checked out first.

In fact, I would bet lunch number one cylinder has a bad valve guide seal from the looks of the carbon buildup. (especially if your compression test was even. and if you had a good leakdown test then i would bet dinner too that it is a valve guide seal versus a cracked ring. And since you ahve the head off then you would be able to see scouring so it is almost certainly a valve guide seal.)
