DL, from my observation of local frames 1800 through 1870, I will agree with Ken. Almost all heavy timber, 8 x 8 and larger, I have seen is boxed heart with sap wood and somewhat lesser amount has wane. Logs were selcted for hewing with the end product in mind with minimal waste and effort in conversion. Big stems could end also be used for radial split shingles and siding.
