I just removed my slides that I thought were going to be impossible. Your definitely right about the heat, but I used a trick posted elsewhere on the forum. Fill the sink up with the hottest water your tap can put out, drop the carb in there for 1-5 minutes, and the slides pop right out. No torch needed. Or if they are real stuck, you may need to boil up some water. I didn't have high hopes for this method, but the carb bodies expand really quickly with the heat from the water fully surrounding them, thereby releasing the slides.
