While it doesn’t really fit your credentials, I can’t help but to suggest Street Trash. It’s not very gory, and what gore there is looks more funny than anything else…but just give it a try.
Blood Sucking Freaks is also excellent, if you want some damn imaginative things done with gore. Throw morality out the window if you watch this.
For something a little more modern…If you want gore that is poetry to the eyes, try out Inside. It’s mostly just blood though, but there are a few fun surprises. I will add Martyrs to the list. That’s just sick.
Last but not least, check out Philosophy of the Knife, if you got the stomach.
