YES its "best" if you make those changes !!!
Ive used 8 volt batteries before but never was a huge fan of that oddball system preferring to either fix the 6 volt system or upgrade to the full more standard 12 volt instead. However YES they obviously make the starter spin faster well duhhhhhhhh. When there were "real" mom n pop genny repair shops they could tweak up a 6 volt VR for use in charging an 8 volt battery and yes 9 to 10 volts would be more in order for charging voltages. If you happen to have a three brush adjustable genny that also can be adjusted up if its NOT that way already.
The genny produces more if its spun faster and/or more current is pumped through its field windings which is what the VR regulates. A 6 volt genny even with a tuned up VR isnt gonna set the world on fire as far as super high charge rates are concerned, but again YES it can be made to work.
If you have a Low/High charge control light switch system (they were used with cutout relays as the charge control method), the low charge resistor value could be changed a bit.
Instead of buying an 8 volt battery and perhaps tweaking up a VR, if you instead convert to the full standard 12 I think you will be happier in the long run OOPS I SAW YOU ALREADY BOUGHT IT
Best wishes, got any real genny shops around?? If so Id let them make the VR adjustments

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
