Have you gotten into Italian horror? Stuff like Fulci's stuff would probably be right up your alley. City of the Living Dead and The Beyond particularly so. Torso is a fun little gem I saw last year that is kind of crap but has some amazing sequences particularly the last act.
Also Prince of Darkness and In the Mouth of Madness from Carpenter, but you've probably seen those.
I'll check all that out! I've seen Mouth of Madness but not Prince of Darkness. Thanks!
