Are these plugs good for a Thor engine with sequential as well?

Gap set to 6mm?

If you've got sequential you can run 0.6-0.7mm with these plugs, no problems, depending on how long you leave them in (electrode wear increases firing voltages). However you will be better off with long life platinum LPG plugs, Bosch part number WR7KI33S. They come out of the box at 0.7mm and work very well. You will have to order them, even Bursons do not stock them anymore. They order them from Bosch in Melbourne as I need them.
