The best advice so far, is to dry your tobacco. Not only will it likely address the gurgling issue, which is more common with bents, but you will get more pronounced flavors from your tobacco.
I've been smoking pipes for 49 years. My "collection" contains pipes of different sizes, shapes, makers, and eras, covering about 140 years of pipemaking, English, French, Italian, North and South American, factory made, artisan made, wide open draw, traditional draw, inexpensive pipes and some of the finest pipes ever made. I can make any of them gurgle, or not gurgle, by how moist my tobacco is, by how I pack.
Most tobaccos ship with more moisture than is optimal for smoking so that they don't dry out before purchase and they benefit from being dried before smoking.
Before you ring a bell that can't be unrung, try drying down the tobaccos that you smoke. Experiment with different moisture levels to get the balance that gives you the optimal smoke. Experiment with different packing methods and densities. Pipe smoking isn't rocket science, but there are best practices.
