New Year and I've remembered! I think it was to do with heads and the ability to create an outlet or a threaded plug 'ole using one of the core plug locations... when thinking about lowered Speedex radiators.
Although I presume it could also be useful when finding the core plug location is a bit eroded, using a BSP brass bung?
