Seat Saver Valves
Rowe Company is now closed . . . but there's still some of these Seat Saver valves out there. Rowe Part No. 721-63. Rowe made these a special head size and stem length(maybe just a touch longer) so you can move your seat OUT a bit on those old gold, bronze type, panhead valve seats that H-D used in their heads for many years. This may save you the headache of changing, milling and pressing in new valve seats, that can fall out or crack your cylinder head.
