Anyone know the formula, rule of thumb regarding the shrink fit tolerance for fitting starter rings to flywheels? My feeling is to leave the recess on the flywheel 'up' by say 0.010" (.25mm) so as the starter ring cools it 'nips' up, without too much stress on the ring but with enough 'nip' so as not to work loose or spin.

the only one I could find was one for a Fiat flywheel and the oversize for that was 12 thou
You're towards the bottom limit on a normal sized (10") flywheel at that. Between 10 and 15 thou should do the job. I'd go for closer to 15. You'll only need about 200C to heat the ring gear to expand enough to fall on at that fit so you can do it in a normal kitchen oven if you're quick getting it on.
