Sioux yes, Black and Decker NO, or at least check it out very carefully. B&D does not support replacement/repair parts. I have a B&D valve machine, got it out of a local school district bus garage decades ago. First thing I did when I got it was write B&D for owners manual and spare parts list, parts list was like 3 pages of "NO longer available". Yes Goodson has stones, they do you little good if you have no pilots.
Good luck in wanting to attempt to do your own valve jobs.....get some junk heads and practice.
