If you are installing them for nostalgia I understand, but from the pure direction of mechanical strength they became anachronous a long time ago. Epoxy with glass strands is far stronger than any wood. Improperly installed crossbolts weaken the stock, every time. Cut sloppy and fully bedded they will not weaken the wood.
The adjustments of course were about changes in humidity and you must use them in unbedded bolts. Not so much in bedding...
