I tried them in my ARC. Not only did I find the difference very modest, they are so hard to find and if you find them likely counterfeit or previously used so maybe weak. Even if you have none of those problems the stock is so small you will not be able to get ones with matches triodes or that match another well. So the real question is better to get new, strong, even croyed ones with matched triodes (GM) or 6h30dr that are unmatched and have unknown usage? For myself I decided the former.
