Poll on are you running Stock or Modified engines

IMHO stock means pretty much stock. I would not consider a .030 over rebuild with stock parts modified. The changes you list I'd consider modified.

Modified in a performance way, I said basically stock cause most cars aren't 100 % stock anymore so if you a holley instead of factory carb but everything is stock then I would say basically stock, even say you got 340 and use a similar cam even if slightly better I'd say stock.
Generally if you replace parts for performance gain then modified if you use some performance parts as replacement for general repair i'd say basically stock.
