Didn't get new cylinders, just had them bored out so really I'm just seating the rings. Wouldn't think it would be as long as a new motor. But not sure.........
Opinoins vary on that. I have done 95 kit put 25 miles on it and put it on the dyno. Others want 500 min. But most high proformance shops will put their work on the dyno shortly after putting motor together, I would want 25- 50 miles on the motor before dyno. Good luck Hope it pulls some good numbers for you
