In a 1950 Chevy Delux 235 engine with powerglide. Is there any problem using an 8 volt battery instead of the orig. 6 volt? Would anything have to be done if the 8 is used?
You will receive more recommendations to leave it 6-volts than to change. With a well maintained and tuned correctly engine the 6-volt is more than adequate. So, stay with the 6-volts.
Stay with the six volt unless your building a period race car. The eight volt battery came about as an inexpensive way for high rpm, second gear, dirt oval track racers to compete with cars that used magneto ignition systems.
If you stick with the 6 volt, get yourself a 6v battery tender and leave it hooked up to maintain the charge on your battery when not using it. I find that helps a lot. A fully charged battery will give you more cranking power.

Just as a note--as I agree with keep it 6V-- oooh rhymes Anyhoo, back when I had my first car (same 1950 year and same 6V system but diff car in the 80's), that 6 Volt battery lasted for years and even in the dead of winter when my dad's 1985 Chev wagon had to be plugged in, mine would crank over and never needed a jump (not that I could have anyhow) and never had to charge the battery. the generator worked better than I would have thought. extreme cold hit the button, would get one revolution, let it sit a bit hit it again and get two revs, wait and repeat...less than 10 minutes of this cycle it would turn over in 3-4 revs and keep running...and after 10 -15 minutes of idle and run to town the battery would have been charged. I was impressed with the 6V system. hopefully this one I have now is as good (no winter driving it though this time).
