Instead of all 3 at once why not try it on one tractor first. See if it works out for you.
I put the standard Pertronix kit in a 3 cylinder Ford and got years of excellent service from it till I sold the tractor. Then the buyer got several more years of service till he sold the tractor.
It was 12 or 13 years in all that I know the tractor ran fine with it.
