Are you sure the 1954 261 had a 6 volt starter and flywheel? I thought that was the year of changeover from 6 to 12 volts and there were some of both? You may want to count your flywheel starter teeth to determine exactly what you have...that and examine the casting date on the flywheel.
Check your pressure plate very carefully as I had one "rebuilt" and it gave me all kinds of trouble. It turns out that the pressure plate lugs between the plate and cover were excessively worn. A pressure plate can only be surfaced so many times before it becomes scrap metal.
