Bill: is there a significant ring ridge on the cylinders? Usually, if the rings are badly worn, the cylinder bore will have a lot of wear as well, from the dirt that caused the ring wear.

This may not hold true with Pierce’s very hard cast iron.

But if there is no significant ring ridge, I’d pull the piston, and look for stuck rings.. you might be lucky and find the oil ring stuck in it’s groove, and be able to free it up, allowing it to reseat and control the oil currently being pumped up past the rings into the combustion chamber.

You’ve spent the money and time on the head gasket and labor, I’d go ahead with dropping the pan, and attending to the oil consumption.. it might be fairly easy.
