Anytime I have a stockpile of SYP I saw it 1 5/8" X 12" and sticker stack. After it dries, it can be easily sawed into 2X4, 2X6, & 2X8 without any waste. I stand it up on the mill, make a thin cut, flip it over, and then saw out the desired framing lumber. There will be virtually no crown in the finished framing lumber.
One of my customers stockpiled lumber for a couple of years to build his home. We "resawed" the 2X12's and that home was finished in December. The carpenters were very satisfied with the lumber quality.
