I removed the 5/4" T&G Heart Pine flooring from my 1800's home and put down 3/4" ply for a sturdier house/floor. The boards are 8 - 14" and up to 18' long. They were nailed down with cut nails. I cut all those with a sawzall to remove from the joists. Now I'm putting them back, but it seems that most of the boards vary in width from end to end (3/4" in some cases). I might have a 14" width on one end, but 13 3/4 inch on the other end. Should I forego the T&G, put it on my table saw and rip it to a uniform length.... then glue, stape and/or ring shank face nail it? It is an old floor that we plan to refinish, but it's still going to look old, so I'm not sure if it matters that much about the T&G. Is there a problem butting them in most cases and using the T&G only when they fit?

Any help would be greatly appreciated.
