Generally what you find when pulling the head is that the cylinder walls are glazed, normal due to the stock ring width. I would let oil consumption guide this repair, not compression readings. We are all guilty of applying todays expectations to a 90 year old design, model a engines will consume oil, cylinder walls do glaze, valves will leak (though not in this case).Its a human condition, we tolerate, even prize some quirks of it being an early design (manual spark advance comes to mind) but with others we demand efficiency. There used to be an oil slick down the center of every highway, oil was kept on the fuel island at the gas station, a little blue smoke wasn't troubling...till the advent of computerization in design and manufacturing changed it.
