Super Ms (Ms in general) with good tight engines that have real good compression do tend to stretch the 6v system a tad. I have no info on alternators for you as every time I see an alternator on an old tractor I gnash my teeth, and if I get one that has a BIG old ugly alternator hanging out the side like a goiter I rip it off and change back (I love my red tractors just like all the other colors but the green and yellow guys were smart enough to have switched their bigger bore tractors over to 12v by the time Super M's came along!) Although a properly tuned 6v system with a high cca battery will work, here are two viable alternatives if you are concerned about appearance as well as functionality: take your 6v generator and voltage regulator to a shop and have them bench matched for 8v, go to Tractor Supply and grab an 8v battery...the tad bit more will make a difference...or take your 6v generator to the same shop and have it rewound as a 12volt, do your rewire and rebulb and run her hard!
