plugs don't care about voltage .... I spy a ceramic ignition resistor on the firewall, that would indicate 12V, although it appears to have a cut wire on the output .... I'd guess it was converted to 12V when the engine was changed, but obviously it's in need of re-wiring, at which time you can investigate whether everything other than the basic engine items were also converted [lights, gauges, heater]
