I use absolutely everything (well, except for the intestines. Not worth my time or energy to wash the feces out and scrape the mucousal lining off).
Curious, what did you do with the lungs? That's one part that I think was commercially banned for human consumption in the USA in the '70s. Even if it wasn't, it's rarely sold fresh as I understand it does not keep well at all even under refrigeration. Pork lungs are used used in Fillipino (bopis, kilayin) and Cantonese cuisine; Europeans certainly use sheep and cow lungs (Greeks, French, Scottish; haggis, anyone), but I'm not aware of western recipes specifically calling for pork lungs.
Pork intestine, on the other hand, is ubiquitous.
Pig intestines, heart, lungs are all part of traditional cuisine. Even the kidneys and liver are "viscera," and those are completely mainstream organ meat. Brain is also eaten (head cheese).
