Is an N65 a big enough injector size?

I have a few Injectors from Australian Grant Tanks, and these were the earlier type, but a Number 80. I realise that you can improve the performance, and efficiency (and emissions!) by upgrading to later versions of injectors and also the Cylinder liners, but would a N65 size Injector give equivalent power and performance to an earlier 80? I understand the earlier Injector has a different nozzle pattern that gave less efficient atomisation, but fuel volume per injection cycle is what makes power.
