Take note of the Mobile 1 High Mileage products; they all rated SL/CF and have 1000/1100ppm P/Zn antiwear additive necessary for flat tappet cams.  I often find this in 5 qt jugs at Wal-Mart for $23-24.  For Ken I would recommend using the 10W-30 weight in his recently rebuilt engine.  If the oil pressure seems to run too low in hot weather he could move up to 10W-40.
