So, the various models of scope have different lengths and shapes of the front bell, there is no absolute scenario that will 100% tell you it will work that all scopes will clear and have a close minimum height.
The best thing to do is mock it up in place, position your scope on some temporary jig/mount/playdoh or whatever for position and then measure.
If you have a cheap mount that is way too tall, then you can sit the scope in the saddles of it and measure clearance from the bell to the barrel, and then the height of the scope tube to action minus the clearance gives you the minimum height needed. If its a 34 mm tube then see if you can find someone to loan you a set, or even drill a piece of 2x4 lumber with a 34+ mm diameter hole and drop the blocks of wood (or tape them on) and center the scope, this will enable you to get a measurement. Only takes 10 minutes to figure this out if you tools and material.
Or order some $10 rings or something from china and drop them on.
