As long as you are not bothered by any additional mess from oil, the seals are just there to stabilize the tubes.
The dent might be problematic if it is deep enoiugh to rub on the pushrod.
Low temperature silver solder will not holdup to the heat of a muffler. High temperture silver brazing is what needs to be employed.
